Hi all. Just got me a 95 Camaro V6 3.4L and was looking to get a cat-back for it. I saw one locally but it was for a 3.8L. I read that the 3.4L exhaust is 2.5" and the one I saw for the 3.8L is 2.25". My question is can I use the one for the 3.8L on my 3.4L? Thanks and been reading a lot of good info on this forum.

 

The differences between the two are minimal. Nothing a muffler shop couldn'thandle, or you could do it should you have the right tools.In fact, the exhaust I have was made for an LT1 (didn't realize it when I bought it), and it fit.
