Stainless Steel Muffler

Top quality in manufacturing, shipping, and instalation.

Installed on my 08 sport, piece of cake instalation, about 10 mnutes. I am interested in one thing, performance, I could care less about the sound, as long as it doesn't drone or sound to ricey. Sound is ok, you can tell it is not stock, also added K&N pannel filter at same time. Sound could be a little louder and a little deeper, especially at idle. Performance, these guys no what they are doing, my butt dyno, which is usually pretty accurate, noticed a definite increase in torque and HP throughout rpm range. I would say at least 15HP. I can appreciate that these guys were looking for power foremost. I removed the baffles (reducers) that are already installed, and the car had a better sound, but lost most of the power gains. Needless to say I put the reducers back in after about 2 miles.

Roadster Sport 3

I think I might be the first one of install this exhaust on a MSM. Installation was extremely simple, took me about 15 minutes from start to finish, including putting the rear of the car on jack stands. Fitment was perfect, went on super easy. Looks great, and sure to resist corrosion for years to come (except for nut that's meant to hold baffle in place, that already started rusting.)

It does drone, but I don't find it annoying. At wot, it's actually a little quieter than the stock axleback (I have a straight through cat less down pipe, with stock resonator in place). But the turbo noises are alot more noticeable now. The idle has more bass now, and sounds meaner, but if you get your ear close enough to the tip, you'll hear a slight flapping noise (like baby farts). Turbo spool did improve about 200 rpms. The most noticeable noise about this exhaust is that now you can hear the wastegate at wot. More than a few people have been fooled, and though I had converted to external wastegate because of the noise. It sounds very different inside than out, I disliked it at first because I only heard it from inside. But was getting so many compliments from people outside, and following me I finally decided to have a friend drive my car around while I was outside. It's a very distinct racy sound.

Brian was very helpful. I ordered the exhaust on Thursday and it was on my doorstop the following Wednesday! It was very well packaged wrapped in plastic, then filled with spray foam, then plastic again, oh and the tip was specially wrapped too! No dents, scratches, and extremely clean!

I installed this exhaust last night and I think it is amazing! I have driven a mere 50 miles with the Roadstersport 3 exhaust but it is exactly what I was looking for in an exhaust. I use my Miata as a nice weather car and wanted more aggressive than stock but not overly loud. This exhaust is fiancé (wife in 12 days) approved! She said it was the perfect volume, not too loud, but loud enough to make us smile.

Brian at Goodwin Racing is amazing I would highly recommend working with him. I did a large amount of reading reviews on clubroadster.net and listening to hours of youtube sound clips. I am very happy I went with the Roadstersport 3. I plan to add a header, midpipe and intake so I'm sure the sound will change BUT I can always add the silencer for long trips (the drive from Ohio to Deal's Gap). If you would like to know more about this exhaust, email me and I'll be happy to help!

I like many others was looking for something more than what the stock exhaust note could offer. I could not be more pleased with this exhaust. After soaking the 2 bolts over night they broke free immediately. I would add that to get those pesky rubber hangers loose spray some sort of lube onto the hanger studs to add in them slipping off. This exhaust note is deep when on the throttle and NOT raspy like some others I've heard . I haven't heard any drone or buzzing out of this exhaust either. Now to the important stuff . The wife approves of it completely. One of the reasons I bought this exaust was the removable baffle. I havent removed it yet and i may not need to. Not do to this one being loud but rather spot on for my taste. A well made product for a fare price. If you have any ???'s you may e-m me Thanks goes out to Goodwin racing on this one. Jeff

Roadstersport "Q", by Goodwin Racing

[12/19/2009] Reviewed by: Bill Latsha - wjlatsha@verizon.net

Applicable to: '06+

The Roadstersport "Q" is an aftermarket muffler designed for the 06+, NC Miata. It was designed to be a more quiet alternative, but to be definitely a little louder and a little more base.

When I had my previous 02 I struggled to find an aftermarket muffler to suit me. I use my Miata for commuting to work so I don't want any drone inside with the top up, and I didn't want a real loud muffler either. I settled on the Racing Beat Dual for my previous 02 after trying 3 other mufflers. After reading here on the forum about the Roadstersport "Q" I decided to try one. I didn't want to gamble with my money, as I have just recently found a job after being off 7 months. The "Q" seemed like a safe bet. I have also de-rezzed the 06 I now have, so this was a concern of too much noise with the resonator removed. The "Q" is exactly what I was hoping for. It even levels out the loud exhaust noise when the de-rezzed car starts up cold. The "Q" has a nice base sound, but not so base it hurts the ears. I used to play a Trombone years ago, so an "off pitch" bass sound drives me nuts. I have 200 miles on it so far. There is no drone inside when on the highway. It is almost as quiet cruising on the highway as the OEM muffler. When I start it hot or cold, there is a nice mellow bass sound. Kind of like a "muffled rumble". When accelerating, it is definitely louder than stock, and the next step louder than with the re-rezzed OEM exhaust system.

The muffler is different than other aftermarkets. I guess the two stage system with the expansion chamber first and then the fiber packed area just gives it a different sound. It is more bass, and louder than the stock set up, and the de-rezzed set up, but not offending at all. It has a very pleasing sound to me. If you are looking for a little more sound than the OEM or de-rezzed set up, I highly recommend this muffler as the next step. I also have to say the Brian Goodwin was excellent to work with. He replied to my many questions by e-mails, and worked with me as I placed the order. I am definitely happy with this choice of a muffler.

Roadstersp[ort midpipe wich connects the end of the header to the muffler.

The midpipe appears to be of good quality and very nice and shiny. But i am not quite happy with the sound, it has a nice burbble at low rpms, but from 5 and up, it creates a raspy, ricey sound when pressing on the gas. It is also way too loud, and sometimes I have trouble listening to music. I do recoomend it if u like this type of sound, but i didn't. And i want to add that my catalytic converter went bad after 6 months and had to replace it.I do also want to note that i replaced the header at the same time, but i do believe the sound is from the midpipe and not the header. but i could always be wrong. the header does look nice under the hood so i would be hesitant to replace that to find out what makes the ricey, raspy sound.

RoadsterSport stainless exhaust, no resonator

[1/18/2008] Reviewed by: Andy Gamble - lgmbl@ptd.net

Applicable to: '90 - '97 1.8 liter

This is the exhaust that is sold as a racing product, meaning simply that it has no resonator. It is slightly cheaper and quite a bit louder.

I bought this exhaust because a hole had developed in the resonator of my '95's stock exhaust, causing the car to suddenly begin making a whole lot more noise, so I needed to replace it to pass inspection. With this exhaust, the car became slightly louder than the stock one with the hole.

The sound is incredible. I am a musician and somewhat of an audiophile, and I can say that this exhaust has a very musical sound to it. A very wide range of frequencies. It's not dominated by low frequencies like many aftermarket exhausts are, but has a lot of overtones which I find quite pleasing. It sort of reminds me of a brass instrument. Okay, maybe not *quite* that musical, but it is really good. I couldn't be much happier with the sound. The product is very well made, and it doesn't have any major flaws that I've noticed. The volume is pretty reasonable. You can certainly hear the engine, and so can a lot of other people, but it's not obnoxious unless you floor it through a town at midnight. Some people might think it's too loud, and some might think it's not bassy enough, but not me. I've been told the volume is close to a Borla system. Everything fit together pretty well, except that I was missing a mount, but that's not the exhaust's fault. I didn't notice any substantial horsepower gain that couldn't be easily explained simply by the fact that it *sounds* faster. Meh, if there's a gain, it's no more than any other exhaust. Maybe noticeable on a turbo-ed Miata?

This is a stainless steel axle-back exhaust for NB Miatas.

Once myself and a buddy of mine had managed to wrestle out the stock muffler (a liberal amount of penetrating oil helps,) the Roadstersport unit slipped right in with no issues at all. Everything lined up perfectly - there were no clearance issues, it simply bolted up to the existing midpipe, and sat right on the factory hangers perfectly at home. The unit looks magnificent as well, it's a shame you can't really see anything except for the tip unless you're underneath the car.

Verdict on the sound: fantastic! I was actually worried it might be a bit too mellow, too quiet. I was wrong. The exhaust exhibits a deep, but quiet burble at idle (baffle removed.) As you get on it through the rev-range, the exhaust now makes itself known, but never in an obnoxious way - no drone, no tinny fart-can sounds, just the sound of a great small-displacement motor. Performance gains were fairly minimal, as expected, although the butt-dyno tells me it perked up a bit in the 4-6k rpm range. Overall, I'd rate this as an excellent product. Sounds great, gives a minor performance boost, and it's a well-made stainless unit with a lifetime warranty. Two thumbs up.

Goodwin Racing RoadsterSport Race Catback Exhaust

Applicable to: '90 - '97 1.8 liter

Beautiful stainless steel catback exhaust for my 1995 Miata. Non-resonated midpipe and muffler with double wall tip in 2.5" tubing. Includes gaskets, installation instructions... everything needed to get it on and go.

Ordered from Goodwing Racing and received in about a week in gorgeous stainless steel. Installation seemed straightforward but the old bolts on the cat (as we all know) were very hard to get off. I took it to a shop and they were done in about 40 minutes. There was a plug for the O2 sensor (on earlier cars, maybe?) that had to be plugged - since my O2 is in the exhaust header - but that was no problem. Everything fit perfectly and without complaint whatsoever. Seeing the finished product, I was incredibly happy with the result and the product completely.

I'd looked on YouTube and saw the video (also featured in the forums) featuring the RoadsterSport Race. I was a little weary of the sound because I got kind of a rice vibe from it. I went through about 126,000 exhaust threads on the forums before finally deciding, for my budget, on the RoadsterSport over the Enthuza M1 Budger Racer because the RoadsterSport is stainless steel as opposed to the aluminized version of the Enthuza. Install, as described above, went just fine. Before I even left the shop the owner told me that it sounded very nice. I fired the car up and was immediately surprised at a great rumble and very nice, deep tone at idle. When I stepped on the gas... well, this exhaust is very loud! I was a little disappointed at the raspiness/buzz when I first really stepped on the gas. After a short warm up, though, that was gone from idle to about 4500 RPM. The note is very deep and very throaty, just a great great sound. I got comments instantly from friends ab! out how smooth and incredible this exhaust sounds (even a friend with a turbo/all-wheel drive Eclipse GSX with a full turbo-back exhaust w/Magnaflow muffler said that mine was smoother and nicer sounding!). Even my wife, who claims my singing hurts her ears, says she loves the note. She says it sounds a lot beefier, and I agree. From idle to 4500 RPM the exhaust is really smooth and simply incredible - as in no rasp or buzz or rice. It sounds especially sweet from 3000-4500 RPM. From 4500 RPM to redline it does get buzzy, but the sound is very intoxicating. I can't really say enough how much of a smile inducing modification this is. I've never found myself revving alone at stoplights until just now. When you're on the gas it's loud. When you're off the gas the sound just drops - which is very nice when you're cruising. As far as power is concerned, who knows? I didn't "feel" any extra HP, but I did notice that on a nice open route that I take scenic drives on eve! ry weekend, I kept finding myself going faster than I usually ! go. I d on't know if it's extra power or the fact that I love hearing the exhaust note. All in all, I couldn't be happier with this product. After getting this exhaust, I was very happy I didn't drop the cash for a more expensive system. I don't feel like I "settled" for anything. If I had an unlimited budget, I would definitely pick this exhaust up ASAP and not think twice. Speaking of unlimited budgets, where are those turbo reviews...

Goodwin Roadster Sport Midpipe for 99-05

Applicable to: '99-'05 1.8 liter

Goodwin RoadsterSport Stainless Steel 99-05 Miata Midpipe with High Flow Catalytic Converter And Resonator PN 11-1001. This is a two piece design with a slip joint for easier installation.

The item arrived well packaged in a timely fashion. There were no scratches, but the male end of the slip joint was damaged (dented in - not round). This was easily fixed with a pair of pliers and a little finesse. Being on the inside of the slip joint I didn't think of it as a big deal. >From the polishing process there were still remnants of the polishing compound in several locations that required removing. The hardware provided with the midpipe was not all stainless steel as implied in the writeups but more than sufficient for bolting together the system. I would have provided stainless hardware that won't rust to go with the rest of the rust free product - didn't seem to make sense to me. Mating surfaces are not machined to receive a flexitallic gasket similar to the OEM one. Due to the increased diameter over stock, the stock gaskets will not work and a flat gasket is provided. This seemed to provide an adequate seal.

Not a bad product, but with a little more attention to detail could be a great product.

The Roadstersport RACE exhaust comes with non-resonated midpipe, muffler, and all required hardware, gaskets, and instructions. The complete exhaust is highly polished and looks incredible. Flanges are thick and the hangers are well mounted. The tip for this particular muffler is 3.5" double wall.

Install was very easy and everything lined up correctly with good clearance between the OEM chassis bracing and axle shafts. On my 95, I removed the rear subframe bracing (6 bolts) to make removal of the oem unit easier. The tip is perfectly centered in the factory bumper cut-out. You'll want to lubricate the rubber hangers with WD-40 or similar to help slide the hangers in and out. I soaked the factory nuts with PB Blaster and they came off easily.

This exhaust is very loud, especially when cold, and after being driven several miles the sould mellows out a little. However, it is still loud, most noticeable during WOT starts or agressive driving. I have a Borla on my 1.6L Miata, and this Roadstersport RACE is louder and raspier than the Borla. This is installed on my AutoX car, so I wanted something reasonable priced, free-flowing, light and simple, and that is exactly what I got. I wish it was available with a removeable baffle or silencer for the tip.

High Performance stainless muffler for 2002 SE

Great Product! Beautiful stainless finish and perfect fit. Took less than 45 minutes to remove the old muffler and install this one. One jackstand at the driver side rear is just enough room to make it an easy install. I installed it w/o the sound baffle that was included to provide a more aggresive sound. After installing, the Miata sounds great! It now sounds a lot deeper and just slightly louder than stock. Some of the previous reviews mention that it gets slightly louder after break in, but I won't mind if it isn't too much. If so you can always put the baffle back in. I bought this based on the previous reviews in this section and am certainly not disapointed. Next up the midpipe and JR header, in preparation for the addition of forced induction. (M45) I don't know if a muffler alone can add very much hp, but throttle response does seem slightly better...or am I just on it more so I can hear the exhaust???

Shiny stainless steel muffler and tailpipe

Installed 0n a 2001 SE. I was looking for a "vintage" sound, and based on the reviews on this page, I decided on the RoadsterSport 3. I had heard some bad reports about the durability of the muffler, but Brian Goodwin assured me that they had a new supplier, and those problems were now solved. So I took the plunge. About $300 and a week later, a big (and suprisingly light) box showed up on my doorstep. The instructions were pretty clear, but Jonathan Tang's write up in the Garage (http://www.miata.net/garage/exhaust/index.html) was really usefull as well. I had a friend come over to help. It was nice to have one guy lay under the car with the muffler on his chest while the other guy fiddled with the attachment points. Install took about 45 minutes, most of which was getting the old one free. Dishwashing liquid lubrication is a must! Looking at our handywork, the shiny tailpipe tip really is beautiful. But when I first fired the car up....it didn't really sound that different. I'd read that sometimes it takes a while for muffler to break in, so I drove and waited. After about 200 miles, it did get louder. Not "wake the neighbors loud" but it developed a nice bass note - kind of a growl - that gets louder when you put your foot in it. I do find myself having to play the radio just a little louder so it can be heard over the exhaust when cruising, but not so much as to be a problem. My dad, an old Austin Healey fan, confirmed what others have written here. That's the sound you end up with. Verrrry nice. I didn't feel any difference in horsepower or throttle responce, but I did notice that now that I can make cool noises, I tend to drive it a bit more....aggresively. Funny what a noisemaker can do. Is it worth it? Depends. If you want to impress the teenagers at the stoplight with V-8 noises, probably not. But if you think a roadster ought to SOUND like a roadster, this may be the exhaust for you.

Applicable to: '90 - '97 1.8 liter

2.5" stainless steel cat-back mandrel bent exhaust system with a 3.5" double-walled tip. Includes muffler and piping with no resonator. Also includes installation instructions, gaskets and hardware.

This exhaust is LOUD. It is very raspy and buzzy between 3 and 4 thousand RPMs, and sounds very agressive from 4 to 7 thousand RPMs. Burbles and pops very nicely on deceleration. There's no droning on the highway (between 3 and 4 thousand RPMs) but it is significantly louder than stock at cruising throttle. Installation is straight-forward, and fitment is generally good; however, on Miata's equipped with a factory rear sub-frame brace, the piping just before the muffler sits a bit too low, and it rattles against the rear-most brace. I can't say if there's a noticeable increase in power, but it does feel as though it revs just a bit more freely.

I bought the Race version of the RoadsterSport knowing that if it was too loud, I could always swap to the resonated mid-pipe. Also, the race version has (in my opinion, at least) a better looking tip than the standard RoadsterSport, which has a hole in the bottom of the tip for a baffle which I knew I would never use. I researched exhaust systems for the Miata for a long time, and decided that I wanted something more aggressive and louder than a Racing Beat, but without the ugly tip of the Borla or the Magnaflow. I like the sound of this exhaust - it's got a very "vintage" tone to it - but it's just too loud for me to handle on my daily driver. While it was fun at first, I will definately be swapping the mid-pipe for the resonated version ASAP.

A really superior product. The polished stainless steel is beautiful, it is unfortunate that you can only see that tip when it is installed. This sound without the insert is exactly right. It is very civilized and exceptably quiet around the neighborhood when kept under 4,000 rpm. Above 4,000 it is just right outside of a neighborhood. A wonderful deep resonance. With the insert installed it is too muffled and quiet. I took it out immediately. In terms of performance, the throttle response feels much improved and the power feels noticeably improved. It feels like it really woke up my car. My only concern is the mid-pipe resonator, being much larger, is lower than the original. That said, I have not had any problems with it.

Good-Win Racing's new RoadsterSport 3 catback exhaust

First, Good-Win was a pleasure to deal with. I had ordered the RoadsterSport 2 which was on backorder. Brian Goodwin e-mailed me and said they would send out the new version in its place. The product was very well packaged and I was pleased to open my foam injected box to a gleaming polished 304 stainless steel exhaust. I gasket was also included with the exhaust. The instructions were all written as opposed to graphical, but still very clear. As I did not have the facility to do the install myself, I called a local muffler shop. They did the install for $30 in under 30 minutes. Now for the sound/performance. The sound is simply awesome. I chose this exhaust after extensive research and ultimately from the previous reviews on this site. The sound is deeper and throatier... However it doesn't drone like all of the Hondas you here these days. I would agree it sounds more like a 60's british sports car. I didn't think I would notice any additional power/throttle response gains, but I can tell you I seem to notice a much greater mid-range power response. Let's not forget the new looks. How can you compare a shiny stainless steel exhaust to the stock exhaust?

Fully polished 304 SS exhaust system includes mid pipe with resonator and muffler

The system arrived within a week and was well packed. New gaskets were included as well as a bolt plug for the oxygen sensor mounting hole in the mid pipe which my 95M doesn't use. (Oxy sensor mounts to down pipe from header in 95 cars) I had sprayed the original OEM bolts/nuts on the aft end of the cat with Kroil for several days before the new system arrived. They came loose with a little help from a 20 inch "persuader" bar. Dishwashing detergent worked into the rubber hangers and a little help from a srewdriver inserted all the way through so that it slid up and over the mushroomed head of the OEM hanger bars helped them to slide out of the rubber hangers. The Roadster Sport fit up perfectly with no need to cut, trim, or move anything. This exhaust is also a little lighter than the OEM despite the larger diameter for all you weight conscious racers. Included instructions were clear and very easy to follow.

It's almost pitiful to hang this nicely polished exhaust underneath the Miata where it will seldom be seen. The sound is absolutely perfect. While this is a subjective opinion, every club member who hears it has made the comment it is the best sounding exhaust they've heard on a Miata. At idle it is a smooth low burble/rumble quite reminescent of the Austin Healy 3000 series straight six's of the 60's. On acceleration, it comes alive at 3000 + and you definitely know it's not OEM. Not obnoxious in any way, just a hollow throaty sound of power being generated. No "rice" like screaming or wake the neighborhood Harley straight pipe noise. Just smooth and soulful. On the hiway, no drone at 60, 70, 80, etc.,where you don't want a loud system. You can't go wrong with this exhaust system.

High Quality Stainless High Flo Exhaust System.

After an exhaustive research of Borla, Thermal, Racingbeat and FM for a system that would offer the quality, performance, and sound I was after, the Roadster Sport 2 suddenly immerged as the clear choice. Installed the unit on a 2001 and like the other comments, I couldn’t get over the mirror finish. Without jacks or ramps, had the old system off and the new one torqued in place in 20 minutes. I found laying a folded towel over the old tip provided adequate protection of the bumper during removal. Then, starting at the rear hanger closest to the tip and using silicone spray and a small tip screwdriver to wedge the grommet, I sprayed enough to wet the inside. The old hangers slipped right out. Repeated the same for the other hangers. Hanging the new system was even easier since the stainless hangers have a slight bend on the tip as oppose to the mushroom keeper on the old system. With the new gasket (provided) in place, torqued the nuts and star! ted the engine.

Glean from this review what you wish, but to quote an earlier review, "music to my ears..." this person was right on target. The car suddenly has developed just the right amount of pleasing low-end sound. Bear in mind, I was concerned the unrestricted "no baffle" system might be too ghetto loud, but not so. When you get on the throttle, you hear that unmistakable Austin Healey M3000 trumpet without the tinny rice sound. The double walled tip fits symmetrically in the factory bumper cut-out and as far as performance is concerned, well I haven't noticed a discernable difference in either the low end or mid to upper end but then I wasn’t really expecting much with most restriction coming from the cat. The exhaust does compliment the Ingen cold air intake nicely. I gotta admit, this is the best upgrade to date for my M2. My challenge figuring out how to schedule an additional 30 minutes to polish the Roadster Sport 2 during the next detailing.

Good-Win Racing's RoadsterSport 2 Exhaust

With less than 5,000 miles on my 2003 LS, I found the bolts took little more than a squirt of WD-40 and a little effort. It took me a little more time to wrestle the muffler out of the rubber grommets, but found that WD-40 and a thin-bladed screwdriver do the trick. Rather than taping a rag or sponge around the tailpipe, I found that a "wash mit" useful, pulling it over the outlet and worked perfectly. The muffler went on even easier, with a "repolishing" of the beautiful finish taking longer than anything before I pulled it off the ramps. Once everything was wiped clean, and the bolts torqued, I took it out for a drive and immediately fell in love with the upgraded exhaust note. It could best be described as music to my ears! Now the question to answer is one concerning intake upgrades...do I want to muffle the new exhaust note with the sound of air rushing through a Monster Flow intake?

Having looked through all of the Miata upgrade catalogs and this website for information on aftermarket mufflers, I elected to purchase the Good-Win Racing RoadsterSport 2 muffler for my 2003 LS. With an initial desire to upgrade to a dual exhaust system, I elected to stick with a single tailpipe in case I ever sold the car (doubtful) and the new buyer was more conservative. In addition, I was concerned about the "overly large" tailpipes that seem to be on most systems. With some very "sound" advice from Brian at Good-Win, I elected to go with the RoadsterSport 2 because of the tailpipe size, and the fact that few people use the insert...telling me that the standard system is not too loud.

Roadster Sport Exhaust for M1

[2/15/2004] Reviewed by: Bruce Stanley - bstanley53@cox.net

Applicable to: '90 - '97

Polished stainless steel exhaust from the catalytic converter aft. Midpipe has resonator, exhaust tip is shielded and not too big.

Installed for about 8 months on my 95. The midpipe that I got with the system had an alignment problem. The flange that bolts to the muffler was not set properly prior to welding so the pipe protruded past the plane of the flange. After time, a leak developed that could only be bandaided by replacing the gasket, over and over. I talked to Brian Goodwin, he told me to bring it over. He had one of his business reps come down to take a look, made note of the issue for QA, then replaced the midpipe on the spot. They even installed it for me. No leaks since, problem fixed. The current midpipe hangs a little low. I also have an aftermarket Cat. The low hanging pipe is probably the result of the Cat and the midpipe being slightly different length than OEM. I think my cat might be a little long (1/4") causing the midpipe to hang low, but I can't be sure since I didn't measure before discarding. This is an issue for a lowered car over speed bumps (I hate that gr! inding sound).

GREAT sound. On the website, Brian states that the M1 design has been under development for over a year to get the sound right. I don't believe there is another exhaust that sounds anything like the Roadster Sport. It sounds fantastic. Not too loud for general driving, definitely speaks up when you are on the throttle. Burbles and pops. A perfect bolt-on for an old school sports car. Kudos to Brian for great support and a superb, well executed product.

Great build quality. Great Fit and Finish. Easy install.

I had a Borla on my 95 and loved the sound. The sound on my stock 03 was very tame. Based on the responses on the list, the price, and the ability of the unit to suport normally aspirated and boosted engines, I got one. Great sound. Easy install. Gets the snarl back. Not sure that it added many ponies, but it seems to pull up hills a bit better. Don

Good-Win Racing RoadsterSport 2 Exhaust

Aftermarket exhaust

Beautiful to behold, I'm tempted to polish it when I wash the car! Installation took about 30 minutes. It has a bass, slightly more open tone at first start up. After the first drive I thought the sound was quite nice....mellow and mature as I had hoped, yet quiet enough at low revs that I could back the car out of the garage without waking my daughter sleeping in the bedroom above. After two or three trips, I began to think it was too quiet, until the next day when I left for the Pebble Beach Concours.

After the first 200 miles or so, my friend and I kept looking at each other, thinking: "Is it getting louder?" Indeed it was, and now after about 1,000 miles, it's absolutely perfect. Between 4,000-4,500 RPM it really comes on, and is screaming appropriately though smoothly near redline. If you're between canyon walls or on a mountain road it's spectacular! Yet below 4,000, when driving calmly in town, it's very civilized. Can't speak to one's ability to hear the radio (my Club Sport doesn't have one, of course) but with the top up there is even less of a difference from stock. If these are the characteristics you're hoping for, you won't be disappointed!

Applicable to: '90 - '97 1.6 liter 1.8 liter

Polished 403 stainless steel cat-back with double-walled stainless tip

The first 500km or so on the new exhaust were quite loud, and the 3000-3500 RPM drone was a bit much. Thankfully, after that, it's taken on a much more pleasant character. It still has a fair bit of drone around 3000 RPM under load, but it's far from headache inducing. Above 3500 RPM, however, this exhaust really shines. While engine braking, there's a nicely pronounced rumble and burble, especially with the foot resting gently on the gas pedal. When jumping off the gas for an upshift, there is often a pop from backpressure, and when blipping the throttle for downshifts, the exhaust has a menacing bark. Cruising at around 3500-4000, the exhaust is as quiet as can be expected, and has a pleasant note to it. I've commuted to work with it twice, once with the top down, and once with the top up. The volume is comfortable either way, and the fun noises make the constant stop and go actually enjoyable.

To sum it all up, I would say this is a great exhaust for sporty driving, or a daily driver. Many thanks to Good-Win Racing for taking the extra time to produce a great product.

Good-Win Racing Roadster Sport Exhaust - Polished, bolt-on exhaust featuring a 3 inch tip with removable baffle.

Installed on a stock, CA emissions, 99. Installation took about an hour with simple hand tools - ratchet set, towels, liquid wrench/WD40 and dishwashing soap. An extremely simple installation, the removal of the old exhaust took the majority of the time, installation of the new exhaust was less than 10 minutes.

Installation notes say that break-in is a few days. As noted in the Miata forums, aftermarket exhaust components don't make a lot of HP difference compared to the stock setup, but it seems to help the system breathe a little easier and be more responsive on the 4k rpm range. The sound from up to 3k rpm is slightly louder than stock but much deeper. During extended driving, no drone is noticable, and the volume level seems to return back to comparable stock output. Once the car is pushed harder above 4k, the volume is a little bit louder than stock, but the growl is deeper. Though I don't race my Miata, I'm very happy with this exhaust - nice looking, and the sound adds to the driving experience without gaining too much attention from being overly loud.

Muffler replacement

I did a lot of research before I chose a muffler for my M2. I'm not interested in making noise, only increased power. This unit is perfect for my needs. The sound is pleasant; deeper than stock and not much louder. Fit is perfect and it takes less than 30 min. to install. Workmanship is excellent. It's almost a shame to put this thing under a car!! Seems to be a good compliment to the R-Speed intake. A header will probably round out the performance mods after I sort them out and save the cash.

Excelent quality. Installs very easily, best aftermarket add-on I have ever installed. Absolutely no after installation problems. Sounds slightly louder than stock, but lower tone. Gas mileage went from 29-30 to a solid 32. I drive 80 miles/day, 50-60 mph, few stops. Can't say if it feels stronger, but looks great. Don't install restrictor.

Polished stainless steel muffler

The thing really is a beautiful site. The finish is flawless and the constuction was first quality. The only problem is removing the old unit. After a few choice phrases the old muffles came off. Yes I soaked the nut over night and they came off easily. I used silicone spray on the hangers, but still had to pry them over the ends of the hangers. The new muffler went on like a charm. The sound is better than stock and only a little louder without the restrictor.( I still hear my monsterflow intake) Very noticible seat of pants increase in power without loosing low end. Great value. Now to find the money for a header.

This is a gorgeous exhaust that sounds great and fits well. The exhaust is only a little louder than the stock '99 exhaust. The sound is smooth and deep and not raspy at all. With the 2" restrictor, the exhaust is even quieter. I'd recommend this to anyone looking for a free flowing exhaust with and awesome, slightly louder than stock, sound. The tip is 3.5" and may be too big for some, but it doesn't stick out past the bumper.

Goodwin RoadsterSport exhaust for my 02 vivid yellow Miata LS.

This exhaust arrived about 3 weeks before my car did, giving me sufficient time to marvel at the finish of this high quality piece. I almost didn't want to install it on the car because it really looks *that* good. I went ahead and did the install with just 9 miles on my car, and am very pleased with the results. The tone is deeper and more powerful, but not loud or boomy. It's one of those exhausts where you know it's there, but it's not something that makes you wish it wasn't. Installation was simple and quick. There wasn't much initial clearance between the tip and the muffler, but a quick test drive allowed the exhaust to settle into place and have more clearance. I can't really judge the performance gains, as my car was literally brand new when I installed this. The sound and finish alone is worth the price. I chose not to use the optional restrictor plate.

I highly recommend this exhaust to anyone looking for a high quality piece for their M2. Brian Goodwin was a great guy to deal with. His instructions were clear and easy to follow, and his exhaust was made with unparalleled attention to detail. I can't give it enough praise. I'm sure it will hold up quite well over time. Feel free to email me for pics of the install.

It's a polished stainless steel glass-packed replacement muffler. Comes with a restrictor that can be installed in about 1 minute to increase backpressure and further reduce noise.

The instructions are clear, even to the part about cautioning the installer to wrap the muffler tips (old and new) to prevent scratching. It is a new car, so everything is clean, and the two bolts holding the muffler flange weren't overly tight. Installing the new part is easier than removing the stock one. It's more like a jewel than a car part. Very shiny, beautifully made and finished. The sound level is reasonable, slightly louder (without the restrictor) than stock and a little boomy at about 3000 rpm. Virtually unnoticeable at highway speeds. Outside the car, it's a deeper tone than stock. The engine seems a lot more willing to rev to redline now. Very pleased with it. I was very concerned about noise, and this isn't very loud. Miatae mufflers are very visible; this one looks good. I'd buy it just for the looks. Top notch service, too. I e-mailed Brian Goodwin half a dozen times with questions and he responded within a couple of hours each time.

Watch out that the tip doesn't touch the bumper cutout; install the muffler but don't bolt up the flange, give it all a good wiggle to let it settle down, then bolt it together. Supposedly, the same muffler is suitable for all levels of performance from stock motor to turbo or supercharged, with changes in midpipe and restrictor.

Stainless Steel performance exhaust sold by Goodwin Racing.

The quality and construction is excellent. The exhaust note is very quiet for a performance exhaust. I believe that the exhaust may be quieter than the stock exhaust during highway cruising speeds. I also added a header at the same time, so I'm not sure about the performance results.

At a price of $250, it seems to be a great buy! Since I don't have any dyno info of the before & after, hard to say the measurable performance results.

The Roadster Sport Muffler is incredible. The finish is flawless. It is a shame that it is hidden underneath the car, it is a work of art. The sound is retro sports car, like the British cars of yesterday!

Installing the muffler was a piece of cake. Followed the enclosed instructions. The removal of the old muffler and installation of the new muffler took less than 20 minutes (used ramps). I highly recommend the use of dish detergent for the lubricating the rubber grommets and the muffler hangers.

Took the car out for a test run. I was impressed! The car is quiet when driven normally. There is a transformation when "on throttle", awesome sound, deep growl! Not intrusive at highway speed. Car feels more responsive from the low to top end! Great addition to my MX5. It is great to do business with a person that deals directly with his customers and provides outstanding products. Thank you, Brian, you are number "One" on my list of MX5 aftermarket providers!
