I have seen them in chrome and black. They look good and sound awesome. I have thought about those too, but I also like the symetrical look of duals on a bagger. If you go to the V&H web site, they have a pic of a RG with black radius
I had the "toilet bowl" bassani heads pipes. I liked them but went to a fatcat at the time. My friend runs them now and they sound sweet. Fitment was very good and I liked the look. You will lose a small amount of low end if you have a stock or very mild build, but not enough to justify not getting them as they do sound great. I had sampson slip-ons but the rineharts wiould probably sound even better.
