98+ LS1 Exhaust on ls1 3rd gen...will it fit?

i am going to put an ls1 in my 92 firebird from a 02 Camaro SS, is it possible to use the full exhaust from the SS/what do you have to modify?

BTW: I DID A SEARCH... WITH NO SUCCESS

It's not just going to bolt up. You'll have to modify the hangers.

The rear hangers for the muffler and tail pipes will line right up. The hanger on the tranny is a different story.

I still think you will end up modifying your stock Y so that it will bolt to the exhaust manifolds, then meet up with the cat back just past the trans.
