i mean i'm no mechanic and someone correct me if i'm wrong, but this is what i understood. basically you need some backpressure for power. if you allow it all to escape too quickly, as in putting straight pipes in the 3.0, there will be little or no back pressure created, and you will lose that power, but it will sound great. the x pipe allows the two pipes' exhaust to mix in then split back in to two pipes, creating back pressure, and no loss of power (possible increase). it might all be in my head, but i feel a bit of a power gain when i hit the throttle after putting the x pipe.
