The H pipes in my Bullit roar and rumble, I love 'em. BTW what comes stock on a GT? H pipes came stock on the Bullitt.

why when im full throttle does the exhaust flare kind of? (21/2" mangaflow xpipe).. is that because i still have a stock catback?

All of you with o/r h pipes have any popping noise at low rpm's?

Damn buddy, and who says it's your thread? And 2k1 is right, if you look around for 30 seconds you'll see tons of threads on this topic, everyone who comes on here now should know the difference because it's been posted a hundred thousand times. And obviously you're gonna get a biased view on the subject because other people have their own preferences, depends on what you like. If you like the loud, raspy sound, go with the X. If you like the deep, low rumble sound go with the H (not to say that the H pipe isn't loud)

I just talked to a muffler shop and they said that turning off your post cat o2 sensors is bad for out motor. Any oppinions?

i would go h pipe if you sre going for the more choppy sound and i would go for the x pipe if you are going for the more smooth sound and a little more hp.

i have an o/r x and i love it! it's not as "raspy" and high-pitched as everyone says they are.....well not to me at least. i think it has a more racy sound.

now just to get rid of these flows......

IMO i would have to say the H pipe. there are many many mustangs around here with X's and H's so i've heard them both a good bit. the X get's real raspy at high rpm's and has an overall higher tone to it but you get better flow out of it. the H has a way nicer sound, it's deeper and more "muscle car" sounding. it's really a personal matter... if you don't care about sound at all, go with the X because you'll get better performance out of it, but if you want it to drive by a parking lot full of people and make them cream their pants, go with the H.
