Exhaust Questions - Third Generation F-Body Message Boards

Ethan91 · 09-12-2009, 06:40 PM

I plan on doing an LS3 Swap, before to long. I have read that no 4thgen long tube header will fit, but what about a 5thgen? I know they are very much alike, but maybe just enough different to work. Exactly why wont the 4thgen headers fit? I plan on getting Hawks K member. Here's what I'm wanting.

Also, does anyone other than hawks sell an exhaust kit for these swaps?

The routing is different on 4th gen headers than on thirdgen headers. 4th gen headers will hit the frame and/or the steering linkage, etc. I imagine 5th gen headers are the same way. You need thirdgen specific headers.

Oops, I didn't pay attention to the original post very well, obviously, but I'll leave the link here anyways:

Do you specifically want tri-y's?

OK that's what I've been reading, but a few posts threw me off a bit. Thanks

I have seen those, but they seem troublesome from reviews I've read. Especially with an automatic and I am going that route.

Will 4thgen shorties fit no problem? (On an LS1)
