according to the rep, the backpressure is generated by both the cats and the H,X pipes. so if i swap out the Hiper's H-pipe with the Stillen's X-pipe should i regain all my torque back? the stillen x-pipe is 2.5" diameter. the cost is around $300 for the x-pipe alone. yikes. one important question though. will the flange points be the same for the x-pipe connecting to the hiper mufflers? if so this is an easy swap. if not, then i'm screwed. please give me so advice. thanks.
