Graves Motorsports hand-made-in-the-USA carbon fiber slip-on silencer for the Yamaha YZF-R6. The exhaust sounds great and is not too loud despite removing the stock exhaust silencer. This is because a majority of the sound damping is handled by the muffler under the bike not the exhaust silencer on the side of the bike. System gives an overall weight savings of 1 lb. compared to stock exhaust system.
