So I’ve got an after market cat back exhaust. Seems to be custom fabricated 2.5" or 3" piping, not completely sure yet. But what I wanted to ask was if anybody knew where I can get a test pipe for my 91 LS? Anywhere but ebay. I’ll use ebay if it’s my last resort but if anybody can drop me a line and provide a link to some usefull information that would be great. Also does anybody know if password:JDM.com still get their test pipes if their out of stock or did they stop selling them? I spotted one at that site but it wasn’t available so I’m just wondering since they are illegal that maybe they stopped selling them.
why risk getting caught? just buy a high flow cat and call it a day. you’ll only see about 1 or 2 horsepower from a test pipe anyway.
or u can take ur car to an exhaust shop and ask them to make u one, its fairly simple for them to do and u know it will fit. Wont cost much either.
But like Teglover said a testpipe is useless if ur car is stock, even with bolt-ons i dont think it makes much of a difference. I have a fully built LS and went from a testpipe to a stock cat cause the excessive noise it makes and performance wise, i dont think i have alot of gain to put up with the noise.
not to many exhaust shops in california will willingly remove a cat on a street driven vehicle and weld in a test pipe. If they are caught doing it they get fined. high flow cats usually only run $100. more than a test pipe but cheap if you get fined for removing a vital part of a vehicles emissions system. I believe the maximum fine is $10,000.
this has been covered. a high flow cat and a test pipe are virtually the same in terms of horsepower. dont be a jerk, save the earth.
Magnaflow/Carsound high-flow cats run about $60 and would be the smart choice.

Resonated test pipes are cheap, but would make the tree-huggers angry. These ebay cats are really resonated test pipes, they are not true cats.
