These pipes are on the Road Glide CVO I picked up a week ago. So far I've put about 1400 miles on the bike(rode it home from Texas), and I'm really liking the pipes. Loud enough to sound nice when you get on it, yet settle down to a nice tone that is not at all objectionable at highway speeds. Quality, fit and finish seems very nice, I've looked them over pretty good and the seem well made. Performance is good, gets a little popping on decel, probably because it only has a stage 1 download, I suspect a quick tune/tweak with my Power Vision will fix that part.
Coincidently, I had Dresser Duals on my '11 Road Glide Ultra till this spring, when I switched to a 2-1, and then traded the bike off. It's hard to go wrong with V&H stuff, it really is, I've had a couple pipes from them and always been happy.
Choose between the 2??
I'd say Rineharts, based on the crossover pipe and the left side pipe not being pinched down where it goes under the frame like the V&H is.
Here's a review on that other forum:
