Bonneville Header Change

Recently, Triumph has changed some of their 2010 Bonneville headers. Some of the headers have an unusual weld in the middle causing the header to flare out more than usual. Because of this change our Sleeper Exhaust will not fit properly. We have attached pictures of this new weld. Please verify that you do not have this weld before purchasing a set of our Sleeper Silencers. We are working hard on a solution to fit our Sleeper Silencers on this new header. If you would like to be notified when the new exhaust is ready, please click here.

If you have any questions, or concerns, please contact us.
