JCH........ Forget screwing around with Cherry Bombs and Raptor mufflers. The answer and solution has been clearly explained by JeffB2. Find a reputable muffler shop, get a set of Porters, Smittys or another good steel or glasspack from a supplier, or super quiets from the shop you go to, and have a system built as described by Jeff. I don't mean to sound harsh, But there's alot to be said about doing it right and correctly, the first time.
Then, enjoy driving the car.
