The X pipe is not as raspy as long as it has cats. If you get an uncatted X it is raspy as all hell. The uncatted H will give you a lower tone than the uncatted X.
If you want to ditch the cats and want a nice compromise consider the MAC Prochamber. It is an uncatted midpipe that doesn't crackle and gives you a nice clean deep tone.
not tru ive had a catted x, off road x, catted h and off road h and the X pipe is much raspier then the H. catted and un catted.
