X pipe vs h pipe on c 1500

[ChevyC1500]

I'm looking to put a h pipe or x pipe on my truck with Flowmaster super 10's or magnaflows. My truck is cammed with a lunati cam, Holley street dominator intake and it's tbi. I have duals W/ 2 1/4 piping. I don't know really the difference in between the x or h pipe.

The difference is so minimal that you should do whatever you think looks cooler or can be done cheaper.
