I have heard that a off-road h-pipe will produce more torque in the low end, than an off-road x-pipe. Also off-road h-pipe is a deeper sound. Can anyone confirm this. I have an 03 gt stock other than original 40 series flowmasters and a k&N air filter. Im not looking for top end gains. I want sound and low end torque. I do not run it at the track. which would be best for me other than gears, off-road h-pipe or off-road x-pipe? Please help.
