Ive been working at a muffler shop for a while. Ive got a MagnaFlow on mine and it was a touch loud, but when we installed it we cut off the resonator. We put a Catco resonator on it and now I sound like a Grand Prix, only a touch louder. It was loud for about a week until the packing settled in. Just remember, put a better resonator in or its going to sound like a ricer on crack.
