Stacey Davids Gearz. H pipe verses X pipe

..a friend just put in 7 "X" pipes and got his up to an additional 42 hp (7 x 6hp),easily surpassing the 41 hp the H produced!

I am going to add more H's to my system. I was thinking of starting at 1 5/8 and go up to 3 1/2 inch in 1/8 increments. This should cover all the power curves. With a system like this I shouldn't need any other power adders.

The guys on Truck-U probably sell this system. But I will make my own to save some money.

Aluminum H's would will be used for a weight saving. They will be tig welded to the steel pipes using our special alloy wire.

I will also connect all H's with H's to equalize the equalization. It should sound like a roaring church organ and run like the devil when completed
