I currently have a Custom full 3 inch exhaust to a Greddy Sp muffler.. And its still kind of loud w/ a tad bit of rasp when u step on it... Im assuming that the little flex pipe acting as a mid-pipe in my exhaust is made of poor quality steel and im going to replace it with a Dynomax Performance 21050 Resonator... its 30+ inches long !!! this should quiet my J down very adequately..Does anyone have experience with this resonator ? Does a resonator even affect the sound much at all ?
