94GTLaserRC: You are in the perfect situation to do it right, meaning all you need is mufflers. Most people who think American thunders (muffler p/n 942543) sound good but are not that loud, don't realize that Flowmaster p/n 42543 are ten times louder. You can not get these mufflers in a catt back kit, so with an american thunder kit you have nothing compared to welding in some Original 40 Series 2-chamber (p/n 42543)
