This is the wrong questions to ask in here friend! No matter which is better, no one will agree on it. If someone says an X pipe is better, then someone will jump down your throat and say that's wrong and vice versa.
I've used both and I find that an X Pipe works the best form my cars. It gives me a little more low end torque.
But I assure you someone will chime in and call me a liar or say that I'm wrong and say that the H Pipe is better.

you need to do a little research, trust me, with a car like this its worht it..
search around the site, and don't let the opinions of a couple people sway you, unless you just like you decisions made for you. There is a lot of information on this site...
I want to use an H when I get duals, why sacrifice sound for that tiny extra flow, if it makes a difference at all. If you do some research, you'll see that almost everyone here, who has duals, uses an X, so this site is a little biased toward them.
good luck with what ever you choose
