I'd say X-pipe simply because of the powerband you'll be looking at, which is upper RPMs.

i'd also say x pipe because of the fact that x pipes and straight through design mufflers work well together. you're supposed to use straight through design mufflers because the pulse effect that baffled mufflers create can cost you quite a bit of power on a turbo application.

H-pipes are better for forced induction, simply because of the sheer volume of exhaust flow.
