Modified stock 2.5" exhaust
I started with a dual cat Y-Pipe from a 91 350 GTA and a I-Pipe off an IROC.  After a set of header reducers, and some collector rings, I have the setup now.  I am also working on installing a Magnaflow muffler with a 3" inlet and dual 2.5" pipes and some stock 4th gen Z28 tips.
The old stuff.....:-(
