Hi Big50 followers, here we have a reverse meg and power pipe that I made many years ago but have recently had it cerama coated. This coating is super heat resistance and is almost chrome like. I’m happy to plug the people that did it which is Race Coating in Warragul. If anyone is interested in this pipe for K4,K5 XR80 I might be interested in selling it.
