I don't know that any aftermarket exhaust alone improves performance. I have an AFE drop in, superchips programmer and the catback MBRP offroad system and the horsepower gain would be "neigh".

I'm very happy with the JeepSWAG system I recently installed. All stainless. Requires evaporative canister relocation, then moves muffler to it's old location. Also works nicely with the storage cubbie enlargement kit (once the muffler is moved). Nice sound--but if loud is your goal, stick with just about any other brand. And please don't off-road in wilderness areas--it's rude and against Tread Lightly ethic. Finally, top-notch customer service from a forum sponsor.

I put a Gibson on in the fall. Noticeable Performance hasn't changed. It's too loud for this old guy and I'm taking it off and selling it. It's scaring the women, children and wildlife. Personal preference, I'm sure somebody else would like it.
