Ok guys, I have a few questions about H pipes because i want to get an off road H pipe instead of one with cats.
First, does anyone know if the MAC o/r H or the MAC o/r prochamber is louder, deeper, and in your opinon sound better? What are the differences in tone between the two?
Second, Is there a HP difference in the two, or will one of them give me better performance.

Thanks guys

I just got the mac offroad prochamber. It is better then the normal offroad h pipe. Supposedly it even outperforms most x pipes. It is is real mellow at idle but once you give it a little gas it sounds like a beast. I did a lot of research on these items and in the end with the prochamber and love it so far.

OK, i was leaning twords the o/r prochamber also because i have the catted one right now and it is very nice sounding. I heard a lot of people like the MAC H for the sound, but yes, it seems that the prochamber has an awesome sound and performance.
