Not a X-Pipe but a H Pipe.

If you ever take apart that "H" pipe, the actual hole in it is less than 1/2 the outside diameter.....I don't know why GM bothered, as it can't possibly even out the exhaust pulses from side to side as well as any of the good X-pipes do............
A crappy one at that

I've been told the factory H-pipe is there more for sound tuning than exhaust flow. I doubt you'd see a horsepower increase with an X-pipe, but it might change the exhaust note a little.
