Both gains wont be noticeable, go with what you think sounds better.

ok what are good brands and the ones that come with cats on them will they pass emissions?

I like my mac h pipe, no real complaints. And with a catted mid pipe you will pass emissions.

i'm partial to SLP catted X-pipe, SLP lmII cat back system. like 03 said whatever sounds better to you.

i as well have MAC and love it.
SLP would be louder.

if you want deep, get h, if you want raspy, get x

X pipe has been proven to give more HP.

To really break it down... H-Pipe is better for low end torque, X-Pipe is better for high end HP, though they both have similar gains. It usually comes down to what type of sound you like. The H is a lower throaty tone, and the X is more raspy.
