Can someone explain the advantage of X pipe over H pipe or cross over pipe on 2007 Mustang GT

Freshmeat

X-pipes and H-pipes are crossover pipes.
By connecting the two sides of the exhaust system the scavenging efficiency is improved. An H-pipe works very well for this for applications requiring torque; it provides slightly more backpressure, whereas the X-pipe is more efficient at scavenging exhaust gases and therefore is better for horsepower and top end.

So... if it's a daily driver that you're just looking to enhance a little bit go with an H-pipe, but if you really want to get the most power from your exhaust modifications, go with an X-pipe.

I have a 2005 Mustang GT and I took off the factory H-pipe including the cats and installed an X-pipe along with 2 1/2" straights off the original exhaust and finaled out with two JBA axle back mufflers. It sounds wicked and breathes very well. About the "cats" I live in New Mexico and there is no law here about having them. X-pipes scavage the air more efficiatly, that's the way to go.
