In my experience, Flowmaster and quiet are an oxymoron! While it is rather expensive, I can heartily recommend the TTI 2-1/2 " X pipe system with the Dynomax reverse flow mufflers that come standard. The X pipe changes the pitch of the exhaust to a lower key sound and the car will really sound nice while letting you enjoy your stereo . I am in the minority around here, I like flying under the radar !
