Are X-pipes and H-pipes Better Than Straight Pipes on Dual Exhaust Systems?
Yes, it does.

It would've been easy enough to order my latest exhaust with an X-pipe, I didn't really want to change the sound. I don't know as I'm leaving power on the table. I'd be interested in dynoing the car now and then adding an X-pipe and doing it again of course, but, with my horsepower level and 2.5" exhaust I don't think I'm experiencing any restriction.

TCCoA, there's no better way.
