The stock canister muffler.  Check out the restriction of the pipe going in!

You can see the heat shields clearly in this shot.

I soaked the cat bolts with WD-40 overnight.  Helped, but not enough as it turned out.

A peek inside the catalytic converter.  I reused the metal gaskets.
38064
Muffler hanger.  I reused all the stock hanging points.  If you go for the under the car spare tire, you probably won't use this driver's side hanger.

Two Hooker mandrel bends from Summit Racing and some 2 1/2 inch piping from my local muffler shop.  We used 1 and 1/2 bends and 2 feet of pipe total!

The stock muffler out of the car.

Cat end.

I made four of the  cuts with a hacksaw before my buddy Harry said, "Hey lets use the cut-off saw!"  ARGH! ;-)

This was the easy way!

5 bucks for the flange.  Measure, test fit, mark, tack weld.  That's Harry's hand, not mine.

MIG welding looks cool in this shot.

We weren't planning on taking the cat out.  Until we gunged up one set of threads...then sheared a stud getting it out!!!

Here's a real closeup of the cat.  If you take it out, hold it up to the light and look through it.  Amazing really.

Nice threads!

Bad picture...worse stud.  It loosened easily...then seized even though it was lubed and wirebrushed.  We heated it with a torch and used vice grips to take out the stud.  Then retapped and put in new ones.

Clamp and tack weld EVERYTHING.  Don't weld it up 'till you finish it all.

Tacking the muffler hangers.

Here it is all tacked in place.  Is that pipe big or what?

You'll redo these nuts a bunch of times when you test fit.

NOW we weld it up.  Notice all the rotation marks from a sharpie pen.

Old and new.  The new system is a few pounds LIGHTER than the stock system!

I painted it.

It's a stovepipe!  Nope, it's a 2 1/2 inch catback! I didn't replace the heat shields.

A closeup.  It's not stainless, but I can replace it 5 times for the same cost!

Look!!! No ugly canister hanging down!!!!
