X 0r H Pipe comparison tests?

[Ripper]

Does anyone know who has done a comparison test of the different X or H pipes? Preferably ones with cats.

5.0 Mustang mag did a test about a year or so back and the H-pipe w/ cats actually beat the X-pipe by like 1 or 2 HP and a few lbs of torque..
In offroad version though, the X-pipe made more power.
Keep in mind, these were on 5.0's, so take this info how you want to.

I can say my X-pipe with 2 cats made no difference over the factory 4 cat h-pipe. My car ran that same times with both.

Ares,
I see you now have an offroad BBK X pipe. What brand with cats did you have?

Thanks!

[Ares]

I welded in Dynomax Super Converters. They are 3 ways no air tubes, about 13-14"long. Saved myself $100 by buying offroad pipe and 2 cats verse buying x-pipe with cats installed
