Received my 17 inch carbon fiber tri ovals on Friday. Took about 45 minutes to install and gaskets and gasket sealer was included. Rode about 6 hours yesterday with the baffles in. Sound is much deeper than stock and the sewing machine whine is gone. Decibel wise you can hear them a little better than stock when you get on it, but not much louder until you get above 5,000 rpm. Above that, they do come alive a little more, but not obnoxious at all. Cruising you don't even hear them. So far extremely happy with the quality and the sound.
They are a little close to the bags, the left side closer than the right, so I probably have a little adjusting to do. However after running them for over an hour on the trip home, the carbon fiber was cool to the touch and the stainless steel end cap was cool enough I could touch it. Nowhere close to needing to worry about melting rubber, plastic or heating up the paint on the bags.
