hey guys, at the moment ive got a 2 1/2 inch piping for my exhaust, from b4 the cat to the rear, magnaflow cat, flowmaster muffler

mods are..

WAI intake
rk upper lower mounts
about to go on...57mm throttle body
LO manifold,
4-2-1 header
lightened crank pulley

thats wuts on and will be on come this season, ive heard its to big, and ive heard its fine, wut do u guys think, does anyone think i would get more power if i redo the whole thing with a 2 1/4 inch piping? if the difference is that of 2 hp or leven less then im not gonna bother spending the money over again, thanks for any info here!!

well with what you have, you are pretty much at the end of the road for bolt ons, so now anymore mods (head work, cams, nitrous, supercharger, turbocharger) would benifit from the 2.5inch exhaust. So i would keep it, and just start with some more indepth mods.

cams are a nice way to go. compliment the boost. you can always work your way from there. port and polish. etc

but say if i were to have these parts for a long time, its not planned, but say if i did, do u guys think its hurtin me? thanks again

as well as thanks for the info so far
