I just installed the Staintunes on my 07 America, and they are fantastic. The sound is perfect, a nice tone that reminds me of the Rinehart true duals I had on my Road King. Loud but not offensive when you open the throttle, mellow at cruising speed, and definitely sweet at idle. I re-jetted with 135 mains as they recommended, no other changes. Pulled out the snorkel as well. Highly recommended.
