x pipe or h pipe

[03cobrarocks]

If you want to be able to pass emisions and get the most rwhp then which way is better to go h pipe or x pipe? And Which brands are the best right now I have steeda catback so if anyone knows of a x pipe or h pipe that complements it good please tell me

an x pipe will give you more of a hp increase over an H pipe, but the H sounds much nicer and I have been told gains more torque. neither one will be better than the other when it comes to emissions testing. Listen to what other cars sound like, and ask what gains they have gotten. Get what you like, just make sure it's catted and you won't have a problem with the testing.
