I ran a 2 1/2 " exhaust on mine with a high perf. cat and performance muffler (the one with the red roadrunner on it, can't recall the name).
When i first put the exhaust in i ran a cherry bomb with the cat, but it popped and backfired a bit when decelerating. It is FAR better with the high perf. If I had it to do over, I'd probably do dual exhaust.
I love your fan shroud - very sexy. Makes that Vortec look even sexier - Dan's just jealous.
Cheers,
Josh
