Dynomax super turbos... hmm. i have been trying to decide what mufflers i should go with. I am TIRED of the obnoxious flowmasters i have on there now. Unfortunately the Y has rotted thru so regardless i need to get new piping so i figured zzp's 2.5 exhaust was a pretty reasonable price($279). And i have never had any problems with zzp's products. A new slp powerflo exh is almost 600 bucks shipped and im willing to bet its almost as loud as the flows.
