Has anyone run these? How do they sound and perform. Thanks for any info good or bad.

Dogbone, I put a set of these on my 09 Ultra Classic, and really like the sound and the look. It is a deep rumble, but not too loud - can still hear the radio, but you can hear the pipes some too. At the same time I changed to the Monster Ovals, I added a V & H Fuel Pak fuel management system, and changed to the SE A/C. I can tell a definite difference in performance with the entire setup. I don't know how much these slip-on's added in and of themselves, but I do like the setup for a little more  performance and sound.
