5.0 exhaust, which is better h or x?

[John4cam]

i went thru the same thing, i called mutiple people on this and the answers i got were all just sound the prochamber makes 3 more HP then both of them, Hpipe has more crisp raspy sound where as a xpipe has a deeper crisp tone then the H

I completly disagree with this. the H has a deeper hollow sound than the X.
