We use the h because of a few reasons. We like the sound much better. We like the power band of the h vs x better. We got +17 rwhp on this with the h (but did not test an x). On the 11 mustang, +21 with an h, +6 rwhp with an x. Srt8 challenger +44 for 08, +48 for 09 (again, did not test an x here, if you get 20+ you've got a winner). But we like the numbers shown on the h on late model muscle cars.

Normally we see higher rpm hp increase out of an x, and low end tq out fo the h. But the h has been performing well on our latest tests, that's why we've been using them. Not sure if other manufacturers are even testing the h, seems like the x is seen as a tried and true fact in the industry."

This confirms it for me. Now I just have to click buy now.

Very nice!! Can't wait to hear it Lee!
