I have an 89 IROC-Z I'm putting in a LS2 with a Kenne Bell and I'm looking for a catted set of exhaust front to rear with 3 inch tubing.

I also need to work in the intake any ideas people?

 

Good luck on the exhaust side, since your putting a motor into the car that doesn't belong in it you're probably looking at a completely custom job if you want long tube headers on it because a header that is made for a regular chevy small block that came in the car won't bolt up because the LSX have different port locations.
