x-pipe = h-pipe?????????????

[5000cc]

Not all x pipes are the same,according to one of mustang magazine which i don;t remember which one had comparison test and Mac prochamber came out on top but Headman x pipe which came in second place was only one horse less than prochamber and less money.I bought Headman pipe last year and love them.It sound awesome different from H pipe that i had before but H pipe is a lot cheaper.THe only thing about Headman header is it comes in 5 pieces and you have to weld it together which another cost that adds up.
