Resurrecting this old thread.. I'm also liking the Freedom Performance Sharp Curve Radius as a possible contender for my '13 High-Ball. I took a look at the installation and it appears there's no frame cutting like with RPW exhausts. It's a stepped header design and look pretty darn good on a high-ball in black.
