ahh such a bummer. I don't really want to make any changes to my catback. Does anybody have the FI resonated HFC's with the FI non-resonated exaust?

I am trying to decide between the new resonated ARK HFC's and the FI resonated HFC's. If the FI ones have already been proven to eliminate rasp then I will get those for sure. Otherwise I guess I have to take a risk and hope that the ARK cats can live up to what ARK has promised
