Complete exhaust recommendations
I know that the subject of LT1 long tube headers has been beaten to death. However, I would like some recommendations for a complete exhaust system. I want to keep the emissions within legal limits. Does anyone have recommendations for Long tube headers, cats, mufflers, and pipes that would meet these requirements for my 1995 LT1 A4 Vert.

I appreciate your input however, I want headers. I know that someone out there has already done the research and has Long tubes with Cats and I did not want to reinvent the wheel.

I first got a cat back exhaust. Consisting of an X pipe and 40 series Flowmasters with all new piping. Then I Went with the EM LT's. From here you can choose what kind of high flow cat to use. I could only afford to do a little at a time. However if your not short on funds it is probably cheaper to do it all at once because youll only pay for the labor once.Good Luck.

There are no clearance issues at all. That is the main reason I went with EM. They have spent alot of time and testing in making these headers truly bolt on. I can't say much about the heat issue. The engine compartment is hot but not any thing more noticable than before.

Exotic Muscle seems to be the header of choice for LTx motors, with the TPiS header a close second. The rest of the OEM piping flows pretty good except for the mufflers, so maybe you can save a few bucks there. I suppose the main reason to do a cat back would be for durability or weight savings? Good luck on the mods

Probably sick of seeing mine too, but since I noticed that you have an automatic, you'll have to run extension pipes around the transmission and put the cats behind it.
