I have had the D&D rev cones. Sold them to free up some cash and find something different. They sound great but I was looking for a deeper tone. Now running America stockers with all the baffels removed- except the difussers. Very happy all the way around. Nice deep tone. Like the others say, not awful at idle, and they roar when you open them up. I get lots of compliments on the sound of my bike.
