06 - 17 Yamaha R6 stock headers w/ M4 mid pipe and Hindle slip on. Exhaust is off a 2016 R6. Only used for one season. It's in great condition and can be taken apart to ship. This is the clamp on mid pipe and it fits snug w/ the stock headers and hindle slip on. Sounds fantastic! $300 shipped, can work something out for local pickup in Long Island, NY
