So I just picked a daily driver '78 gmc jimmy 4x4 and as always I already wanna mod it http://www.ls1tech.com/forums/images/smilies/LS1Tech/gr_grin.gif. So first things first I wanna get the exhaust done. Right now it has a stock 400 sbc. So im gonna do hooker coated longtubesto 2.5" pipe with an h-pipe run out the side behind the rear wheels. I just cant figure out what mufflers to do. I really have it narrowed down to 3 though. Really want to avoid 40 series flowmaster cause im tired of hearing them on EVERYTHING!
1. magnaflow 14" round mufflers(I already have these)
2.flowmaster single chambers
3.moroso spiral flows.
