Umm not exactly. With an Offroad H I picked up low end torque and power throughout the power band. An Offroad X will lose a little low end torque and will gain 1-2 more RWHP than an H.

Umm, I thought he said an X-pipe specifically...

Would'nt you say an X-pipe paired with a 9:1-9:4 compression ratio will fair better with some back pressure. On the other side, a 10:1-11:1 compression ratio fairs better with no back pressure...in reference to low end torque...
