If anyone is interested in a one off, I am aiming to make a single titanium silencer this month (march) for the Ten. It's a round silencer design as it's easier to get a secondary one for a tool tube if you want. 50mm bore and with a baffle. I will make absolutely no claims for performance, and in effect it will be a slight second as I will be fitting it up and testing it on my bike to make sure it all fits ok and isn't too noisy. It will, however, be an awful lot lighter than the OE. Stainless link pipe as well.
