I put them on my 2011 XR. They sound beefy but not too loud unless you get on it good. I like them lots.
The fit and finish is awesome. I wondered why the tips were so much until I had them in my hand. They are a work of art themselves.
Here's a couple pics. I think this style fits the bike pretty well. I just got back from a 5,000 mile trip out west and the bike was awesome. I took out the fiberglass packing the other day which made it have a little more bark but not obnoxious.
