Since four-strokes came out in pwc scene we have not heard anything about new exhaust systems and Factory Pipe is still selling a lot of these SX-R pipes. Though, someone thought of making a brand new exhaust pipe for Ultra. We have seen this picture at Rogue Jets web site and we are looking forward to hear more about this new project. It nice to see something really new coming up for the Kawasaki four-stroke engine.
