I had SEIIs on a used Wide Glide I just bought (431 miles on it). I have V&H big shot staggereds on it now. At an idle, I wouldn't call the sound mellow. There are loud when I roll the throttle. I think they look most excellent on my ride
I have SE II slipons HD part number80293-99A. At the HD web site the part number for the SE II is 80366-99. Anybody know what the difference is if any? Mine are loud enough to set off car alarms in shopping center parking lots.
