the h pipe will give it a lower sound than the x. it is a lower sound rather that a hollow sound. i think you should go w/ a o/r h pipe bc it'll be louder. i have LT's, o/r x , MBRP deletes, and M80's welded in midmuffler style. it is low and deep and loud, some popping on deccel, but i like that. heres a couple samples.
