i have heard good things about this modification, i am getting new exaust, duals with the X pipe put in, does anyone know how much of an affect it will give me from my stock pipe, with a hole in it (before the muffler) hehe I do know the X pipe is a step up from and H pipe, but i dont even know what that will do. what hp increase will i see, torque, sound, ect.

Thanks

Hi c_creations, hello all,


Two pipes will reduce backpressure and will probably call for a small enrichment of your fuel mixture, which will result in a slight gain in power, throttle response, and fuel economy.
In your case an "X" pipe will be no improvement over the "H" pipe, which will only quiet the exhaust.
