Re: 3800 Supercharged GTP INtake/Exhaust
as far as flow and sound get spintech mufflers they sound outrageous and flow very close to straight through mufflers. they sound good on V6 motors as well. i've heard the way some 3800's have sounded with the wrong muffler, it sounds rice... with a spintech you should have a nice grumble.
