A X-pipe will give a higher pitch sound than the H-pipe. I had a Dr. Gas x-pipe but ended up going back to the H-pipe because I like having the deeper rumble. If you want it, it's for sale. It just sits in my garage collecting dust.
The problem with the Dr. Gas is that it is all welded together at the crossover. So shipping the pipe will be an issue unless the welds are cut. Cutting the welds is no big deal. When it gets installed, have the exhaust shop reweld it. Just give me an offer and we will go from there. Just to let you know thou Dr. Gas pipes aren't very cheap. Anyway let me know.
i just took off a UPR o/r x-pipe yesterday to put on a mac h-pipe for my magnaflow catback. i will sell the UPR x if you want it, it is in two pieces and can ship in the mac box.
X pipe cleans out the sound ...I wouldnt say more raspy, but rather more of a race car sound. It replaces the deep burbling sound of an H with a smoother higher pitch tone ...I love the sound of an X pipe a lot more than the H ...especially with 2 chamber flows
