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?
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. Jer 22:13, 15-17
