Man you guys SHOULD LEARN before you speak out. An H pipe and an X pipe accomplish the same thing, they allow the on-fire order cylinders on one bank to scavange the off-fire cylinders on the opposite bank.

This IMPROVES LOW END TORQUE GUYS. ALOT OF IMPROVEMENT.

An H pipe will give most cars about 4-8 HP. An X pipe is more efficient and will give you 10-13 HP.

If you have one USE IT. By the way, the X pipe or H pipe will also make your car 4-8 db QUIETER. By allowing the off-fire cylinders to equalize into the second exhaust pipe, it reduces exhaust pulsations that generate the "beating" you hear with non-equalized exhaust systems.

Now bolt up that X flow system and ENJOY. IT IS FREE HORSEPOWER WITH NO NEGATIVE CONSEQUENCES.
