Ok. I did some research. Here is what I found. The purpose of H and X pipes is to reuduce the pulsing and back pressure of exhaust from 2 cyl's that fire at the same time on the same bank by bleeding the exhaust into the other side where there is no pressure. That helps torque and hp. The X pipe is more efficient and gives more torque and hp than the H pipe. The H pipe is louder. The X pipe has a lower smoother sound. So if you want sound go the H pipe, if all you are worried about is performance then the X pipe. I decided the X pipe. So now my question is who offers the best X pipes?

The X is louder and has a higher pitched sound, the H is lower and has a deeper growl. I have an X.

Dr. Gas has the patent on the best geometry, since he developed the technology.

Woe to him who builds his palace by unrighteousness,his upper rooms by injustice,making his countrymen work for nothing...Does it make you a king to have more and more cedar?Did not your father have food and drink?He did what was right and just,so all went well with him. He defended the cause of the poor and needy,and so all went well...But your eyes and your heart are set only on dishonest gain,on shedding innocent blood and on oppression and extortion.

I was alittle confused on that. Some people were saying H pipes were louder, had a 60s era muscle car sound and sounded more choppy. Some said they had a deeper lower sound. Also heard H pipes tend to pop more on deceleration. Some said the X pipes are louder, high pitched and more raspy sounding while some said they had a lower, deeper and smoother tone than H pipes. Which is which? And I decided on the H pipe. What are some good H pipe kits?

You have the answers right in your post.

H ="had a 60s era muscle car sound and sounded more choppy, they had a deeper lower sound"

X="Some said the X pipes are louder, high pitched and more raspy sounding"

Bassani, BBK, MAC are some of the companys that make them.

For the six, there are 3 ways of going about it, actually 4

1) pick up and H-pipe adapter from Summit Racing (only because they're the cheapest usually, but you can run a froogle search for Pacesetter Exhaust Mustang Adapter

2) Pick up Spintech's X-pipe which uses Dr. Gas

3) have a local shop make a custom adapter

4) go to any exhaust manufacturer and just pick up the X-pipe portion and have a local shop put together an adapter.

There is an h-pipe adapter from Both MAC and Pacesetter exshaust. Pacesetter is stainless steel and cheaper.
