What does an Exhaust X-pipe do?

What does an X-pipe do?

X or H both are balance tubes which are meant to help the scavanging effect of your exhaust system. X-pipes are less invasive towards flow and tend to yield better Peak HP…H-pipes actually cause a bit more turbulence but to the effect of netting slightly more backpressure increasing TQ.

Honestly I think all too oftern both are arbitrarily placed where they fit best over wher they work best by most exhaust shops. On my  ImpalaSS I had the H pipe welded and removed 4 times until I had the best location. The best location for it proved to be a place not very accomodating to ground clearnace but still netted almost 6 RWHP more over the original location which best “fit” under the car.

I know professional race vehicles spend hours of dyno tuning and complicated math to find the “best” location for these balance tubes.
