Will 4th gen exhaust fit w/ LT1 swap?
The '94 Camaro parts car I got for the LT1/4L60-E came with Edelbrock headers/Y pipe and a Flowmaster catback system. The exhaust on my '91 Firebird is all stock. Can I swap the 4th gen exhaust into me 3rd gen without to much hassle? I'd particularly like to keep the headers and Y pipe if I can. I'm pretty good at fabricating stuff, so minor modifications are no problem. Thanks for the info.

You should be able to use the edelbrock headers from what i've seen, but not the Y pipe, i'm quite sure they are a copy of the thirdgens with just different hookups for the LT1 and a different Y pipe, you'll just have to make some changes to the catback hangers for the exhaust to work.

I took a setup off of a 4th gen and used half of the i-pipe back and made a piece from the cat to connect to the i-pipe.
