X Pipe VS. H Pipe

Okay, I know all you guys have your opinions, but which is actually the best for a 1996 GT??? Mine is basically stock but I want to get rid of the four extra cats and only keep two for emissions testing here in Dallas/Fort Worth...I have Flowmasters, and I don't mind LOUD...just want it to sound good!

In my oppinion X pipes don't sound good with Flows.
An H pipe will go better with Flows but it will be loud.

I would recomend a prochamber.Better sounding and not as loud as an h pipe and you'll get more power from a prochamber.
A prochamber and Flows will sound awesome.
