Exhaust H Pipe vs. X Pipe: Difference?

TeamARK · 03-11-2010, 05:29 PM

To put it simply x flow provides a smoother flow. We were the first to bring the Xflow design into the 370z and we made a designated chamber for this. Other companies seem to have jumped on this by merging two pipes together forming a X.

Thanks all for the info so far.

ARK, I don't doubt that it's good but just curious during the testing did you have a prototype that had both an X and and H? If they were both tested what would have been the benefits as far as tq/hp gains in different areas of the curve? Or did you just go with the X right off the bat.

Also you are right some of the other systems (Berk, FI, ARK, Stillen) use and X. Seems like traditional Japanese tuners (HKS, Greddy ECT) use the H design.

From a 350z post. Honestly, I don't think some H-pipes contribute much to the flow.

LOL that looks really cheese-ball. I don't think/hope most H-Pipes looks like that. I'd be willing to bet the HKS is the full I.D. of the pipe or close.
