My exhaust resoates too much. It has a nice sound to it but I got tired of the resonance, especially around 3krpm. I was thinking about going to Meinekee and asking them to do it. Does magnaflow sell sport type resonators? Also will a resonator impede flow? hmm also my piping is 60mm ~2.36in, will this be a problem? If so should i get a 2.25 or 2.5in resonator.
