On Cody's recommendation I just replaced my stock pipes with a set of Staintunes. Even though the temp around here is a balmy 20 degrees, I had to take them for a shakedown ride. I'm currently running 130 mains and am impressed with the workmanship and sound of the pipes. I only got her up to 50mph before my face froze so can't comment to much on performance yet. Sure like the sound though!
