I am looking into getting one of these Pypes off road H's, but ive heard nothing but complaints. People are complaining about the resonance or a buzzing at certain RPM. I got to thinking, however, that why would this H-pipe be any different from another H pipe and this is about half the cost. I mean mufflers can vary depending upon the internal design but an H pipe is an H pipe.
I was wondering why you switched back to the x pipe from the Pypes H.... Is it the sound or the power which I find hard to believe is really a noticeable difference.
