HKS Superflow

Unique aftermarket air intake.

I purchased this from Performance Buyers Club. It arrived as described. This kit is complete and instructions are straight forward. I did have a little trouble figuring out how to assemble the mounting bracket the correct way, but that was only a minor setback. Install took only about 20 minutes.

The first thing I noticed is that this intake is definately louder than stock. Even at idle. It isn't annoying though. It's a nice growl. Car seems more responsive also. Feels faster, I'd guess around a 5-8 HP gain. I would recommend this intake to anyone who will listen. Will definately buy from the people at Performance Buyers Club again.

HKS Super Dragger

Stainless steel muffler

I bought this exhaust because of its reputation. It was very expensive, around $550, but it was the only Japanese exhaust in the market (the Greddy exhaust was never in stock. If you order, you'll understand). The exhaust is very shiny with a little yellowish, which could be the fact of chromium. The quality is very good, with exact fitting. The tone is exceedingly quiet, just a little deeper around 1000 - 2000. To me, it is even more quiet than stock. I don't feel any lose of torque, but smoother accelaration on the freeway, especially high rpm in 4th and 5th (my car is 6 speed).

If you are looking for a loud exhaust, don't buy HKS. I heard the HKS dragger produces very loud exhaust, but not for the '99 Miata. I am kind of disappointed because it is too quiet. My friend even said he couldn't hear the difference (outside) before and after, just a little deeper. Truly, it is so quiet that I can't even tell the difference. The tip of the exhaust seems kind of big solely, but looks perfect on the vehicle. The quality is excellent, but too expensive for just the rear section.

highly polish muffler with 4inch tip. think the pipe dia is about 2.5inch or little bigger.comes with everything you need. 2 gaskets,bolts. 2 pice bolt on cat back sysytem.

installation was very easy, everything are in stock location rubber hagger, muffler etc. HP gain unknow don't have a g-tech or dyno to measure it. but it felt more peppy then before. deep tones not too ricey. not too lound.

i got this cat back for $650 shipped from NOPI. not really worth that much but the name your paying for. reason why i got it because this is the only cat back exhaust i can find in stock at the time order. could go with flyinmiata or BSP. too many people have that on the Miata already so i want something diffrent.

HKS Super dragger exhaust

Cat-back exhaust, with gray ceramic coated piping, a highly polished muffler and 4 inch tip , piping increases in size from beginning to tip starts 2-1-4 to 3 inch out of muffler to tip

The fit was perfect and all the parts supplied were of the highest quality. It included 2 new gaskets (its a 2 piece exhaust) and bolts to connect it, installation is definitely a diy project. There was a slight smell from the exhaust, but it disappeared in 2 days. The sound is a personal judgement but i couldn't imagine this car sounding any better, it is slightly louder when cruising than stock, but at wot it is truly amazing, definitely loud enough to hear and enjoy. performance is also great above 4k it really helps out, and 3rd gear pulls like never before.

I hadn't been able to find any pics of the Miata specific application but was really pleased with the aesthetics of the system, similar lay out to all other systems the piping is straight thru the muffler, however if you have a 2nd O2 sensor you have to make your own hole, luckily mines a 94.

Excellent quality beautifull muffler all satinless steel. Instal was a snap as is to remove. Very shiny.

Awesome sound not loud and annoying just deep and throaty. Sounds intimidating. You can feel an umph after 5k rpm. A little push. Backfires at times during 1-2 shift and 2-3 but thats cool.

kinda pricey at 500.00 just for rear section but i love it.
