Ordered a pair of Commando peashooter mufflers today. These are made in 1 3/8" or 1 5/8" inlet but I have asked for them to be made to fit exactly on the 40mm Yamaha down pipes. As these are hand made in the UK, you can have pretty much what you want. Spent far, far too much on this motorcycle. But that's just what happens. I suppose.
