We installed a set of Vance and Hines Power Duals and Monster Ovals on a brand new CVO Road Glide Ultra this afternoon and I shot a short video of the sound for anyone interested.

This is a great combo and really does away with the heat combined with the Power Commander we added. Thanks to Jamie for the map!

I would describe the sound as mellow with a robust tone when you really get on it. Perfect for those who want more sound, but do not wish to shake the neighbors windows.
