You don't need cats, mufflers provide enough back pressure. Offroad H will give a little better TQ down low and the Offroad X will give a little better HP up top. Most people with 96-98 Cobra's make more power overall with the Offroad H, dyno wise at least.

This a very debated question, true most people and mag's state the x for hp and the h for tq..It is a well known fact that cobras lack torque...Most of the cobra owners I know, 6 that are in the low 12's pushing 11's NA run X pipes, laroccas recomends them to most of there clients, H pipes are great for sound, but the X pipoe seems to come out the winner for the Cobras, My Dr gas x o/h is on its way
