November 2, 2011Ive been doin some thinking. Ive come up with an idea. Could i get a set of shorty headers, mount the o2 sensor in one of the headers, get cutouts (dump valves) on each header, then run my stock y pipe and exhaust. And off of the cutouts run 3 inch down each side and out before the rear axle. Maybe a glasspack on each.
My questions are:
Would the o2 sensor read right if mounted in the header?
Do i need an x pipe or h pipe for the dual side of the exhaust?
Would i see thte same hp gain if i ran a single dump valve off my stock y pipe and single 3 inch pipe out the back?
