How much will a catback help?
Right now i have a custom made Mandrel bent Ypipe for my Jet Hotts, with no cat. It is welded directly to my stock pipe and runs back to a hooker aerochamber. I love the sound of my car but im wondering if it is holding me back? Is it worth it to get a catback?

On a stock car the larger I-pipe isn't going to help you much, especially since the biggest restrictions (manifolds & muffler) are already upgraded. 5hp at most IMO.

An "All Forged 385, Splayed Mains, LE2 Heads, Brett Bauer cam, Jett Hott LongTubes, CSR Electric WP, 52MM TB, Ported Intake, 30# Injectors, Comp Pro Mag RR's, BBk Underdrive, Spec Stage III" isn't quite stock. It would seem to me that the stock 2-3/4" IM pipe would severely choke a setup like that. It would probably like a 3.5" pipe.

It would be interesting to see what your stock I-pipe would do with a aftermarket muffler with better flow.
