I have a prochamber right now and ive never heard an h pipe before whats the diff between a prochamber and an h pipe my freind has an x and its deep but not an agressive deep i want an agressive deep like a lion speed you know what i mean

 

If thats the sound you want, you should go with an H pipe and sell the prochamber. You wont get the deep, deepness out of the prochamber. Hpipe has the deepest tone. But remember, your catback plays a big roll in the sound.

 

what produces the most power is it x,h,pro or x,pro,h ?

 

o/r x produces slighty more power

 

H for low end, X for top end. Throughout the powerband they are pretty much equal.
