I want to replace my stock h-pipe on my 2003 GT Mustang. I am lost on what to go with on X or H pipe but i want it to be loud and sound very nice and muscle type sound. I already have flowmaster super 40's cat back exhaust. And i live in Arizona and we have emissions testing here. Any ideas???

Definitely the h pipe all the way.

go h-pipe. x will make a little more hp on the top end but the h will sound better

With emissions, make sure it has cats or you will need MIL eliminators.
