X will give you more HP, but only by low single digits at most. Increases are negligible at best though. The differences are in sound more than anything. X will give you more of a raspy/racecar sound while a H tends to give you a deeper more muscle car sound. Don't buy either one if these based upon power increases, be more concerned about the sound you're trying to achieve. A ORX with no resonators and Roush Axle backs will be LOUD and raspy to say the least. It may be the sound you're looking for, but it's not for the weak at heart.

I like the H-pipes better, as they have a lower rumble to them and don't sound as raspy. If you go with a x-pipe with those Roush axlebacks you are going to have some serious rasp, especially if you do a resonator delete. I would advise you don't do that. As soon as I swapped in high flow cats and a 3" cat to axle pipe, my roushes became unbearable.

Roush mufflers sound goo, but I think they are made for a stock car. Once you add stuff that increase the exhaust flow, they get out of hand. I sold mine for RTRs.
