what i did was measure the res that was in my car, it came out to 28 inches long, flange to to the end of the outlet tube. stock outlet is 2.25 inside diameter.
i picked up a 32 inch glass pack cut the inlet tube off one side, and welded a flange on it. made it roughly 29 1/2 inches long. it cost 22, the flange cost 10, the welder got me for 20, new gasket was 6. vs a new replacement walker res for 100 or more locally.
my car already had the stock cat back replaced so all my pipes and stuff are clamped not factory welded.
if you have the stock cat back your going to need to go to a muffler shop, have the old res cut out and the glass pack welded in, unless you can weld yourself.
if your cat back is not stock, un bolt it yeah right, break the bolts from the cat to the res and drop the whole exhaust and then work on getting the res off the pipe. i used a cut off wheel and scored the outlet tube with 3 lines and just pealed the pipe back till it came off.
