Re: Resonator: keep it or lose it...
well IDK about the whole two-pipes thing...but I deleted my reso and love it...I have a fairly-large Borla that gives me plenty of sound without the drone. Depending on the muffler, the reso will reduce the drone...or IIRC some guys delete the muffler(s) and roll reso-only. Hope that helps...
