The S type silencers are not the same as the Roadster ones. Different part numbers, I probably have the numbers if you want them. As others have said, the mounting boss is on the same side for the S type, I don't know if it's in the same position, I doubt it. The shields are held on with another boss on the outside with a BA round head Allen plus a jubilee clip on the front of the shield. You will need a dogleg bracket and other items to mount the silencers. They are a pain in the butt. You have to keep them tight or they will beat your left side panel to death. The clearance above the chaincase is tight. Supposedly the exhaust path is shorter including the exhaust headers so there are reports of them being faster, but that may be wishful thinking. Andover will probably have everything you need. You will burn your leg on them at some point. But they look cool. You will also need a really good clamp for the exhaust to silencer transition. I use ones called "Moose", they can be tightened until you bend the exhaust.
