o/r x or o/r H

Do you have a 5.0? If so, then an X pipe will give you a higher pitch note and more high-end response. The H will give you more lou pitch sound and more low end response.
The same is tru for the 4.6's, but I understand on the 5.0's that it is more pronounced. Off-road just means w/o cats.
