I deleted the resonator, because it was after the rear axle, I still have both catalytic converters. The flowmaster gives you plenty of back pressure, so it's all good.That sounds nice! I want to get a setup like that goin on my 05, however, I have some questions. This might be a dumb one but I've never had vehicle with a resonator so here goes. If do a new muffler can I delete the resonator do give it less restriction. If want good sound but want to do it properly to help the engine breathe best I can. Thanks!
