New on here so you probably get this question alot. Got an 03 snake with 40 series flows on it. I want to go to an off-road X and mid length headers. Car sounds good now at low rpm and romp but i want to shake the ****ing doors off everyone i pass. Whats the best head crossover combo. Dont care about price really. I know there is a long bbk vs. bassani debate. Also which Xpipe comes with the O2 censor hook ups.Thanks
