They sound great standing about 5 feet behind the bike when it's running! In my opinion they could stand to be slightly louder at idle and wide open throttle and slightly quieter at cruise (maybe that's not possible?), but everything considered, I love 'em. (6 into 6 pipes on the Valkyrie was just about the ultimate sound to me.)
Another update, I always check my mileage each time I fill up, and I consistently get 40 to 42.5 mpg in my riding around here and to tri-cities and back. I have topped off 3 times since I put the pipes on and it was 44.4, 44, and 44.4 which leads me to believe the pipes made the engine a little more efficient. (and possibly a little more power?)
