slight difference in sound. x pipe is more high pitched and a little raspy, while an h pipe is more of a deep muscle car sound. x pipe is supposed to produce more horespower, while an h pipe more torque, but the difference is minimal. 1-2 rwhp and torque difference. Just get whichever one you want and like the sound of.
