Well I'm finally getting ready to order headers but really debating what brand to get and what type of crossover pipe, reason I say this is because I need something that will hook-up right at the catback (ARH Intermediate system) vs the long system ARH makes which hooks up to the axleback and than would interfere with the AFM valves/motors as I don't want any codes/motors rigged up under that car. So really looking at the ARH intermediate system with H-PIPE but not sure as it looks like in the picture there crossover pipe starts closer to the headers than something like stainless works or kooks, I just don't want any fitment issues with Hpipe when cars come with Xpipe. It also really comes down to does the HPipe loose more power over XPipe if that's what our cars have??? So many unknowns! I see on this website they say H-Pipe is better for low end torque vs Xpipe better overall flow and better top end (
