I'm running an '06 GT that will shortly be receiving an intercooled, centrifugal supercharger and BBK long tubes. At the moment, it has Magnaflow axleback exhaust, and I'll be trying it out with the blower and headers, but am unsure which mid-pipe to get. It'll definitely be the offroad version, but I can't decide between X and H. I like the X-pipe's ability to better balance the exhaust banks, but I hear that it can create a somewhat raspy sound (like a ricecar). Preferences? Any truth to the "raspy" exhaust note of the X-pipe?
