Since the other place is such a pain to deal with..... Does anyone have any experience with this system? I know that lots of folks have the header, but I can't seem to find much about the cat-back? The only reviews I have found suggest adding a resonator to the mid-pipe to tame it a little. Otherwise, it's very tolerable while driving normal, but gets wild when you enter the high RPMs via WOT. Any kind of feedback will be appreciated.
