having an exhaust dilema?
having an exhaust dilema? So I just picked a daily driver '78 gmc jimmy 4x4 and as always I already wanna mod it 
. 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
1. magnaflow 14" round mufflers(I already have these)
2.flowmaster single chambers
3.moroso spiral flows.
Post up sound clips if you got em, otherwise just post up your opinions.
