Alright fellas here's the deal: I recently installed a Vortech si and I'm wondering much things on the exhaust end are holding me back if any? My setup is as follows. 302 w slightly "worked" e7's w beehive springs, .512 lift on in and ex, stock ho upper intake with ported lower, stock headers, stock h pipe w pre cats removed, the other's were replaced with high flows, and Forzaflow mufflers. Before the blower I was making 223 rwhp and I think like 280 some odd ft lbs. (waiting for tune appt) Since I'm forcing more air in do I need to step up to 2.5 or with my modest combo will the 2.25" suffice? I'm guessing that there would be no real gain if I went catback only. If I indeed should go 2.5" what's the best way going about doing it? Get a 2.5" mid pipe(I want cats due to smell) and a 2.5" catback system? Or is it more cost effective to purchase a 2.5" header back weld-up system? Or how a about having a shop fab up something custom? Labor costs is a factor if that will help narrow down the decision. Oh and no "long tubes ftw" please, ain't happenin'. One more question if I go w larger piping are the chances fairly great that I'll have to get new mufflers?
