The engines of Sporties built up to 2003 were solid mounted in the frame, from 2004 they are rubber-mounted. So the entire exhaust of the later bikes is carried on the engine unit, so it can move with it as it vibrates in the rubber mounts. On earlier bikes the exhaust could be supported at the rear from somewhere on the frame. Does that answer your query?
Mounting is slightly different after 2013 , the rear master cylinder position has changed.
2014 and 2015 are different from all previous muffler mounting styles.

There's a whole lot of accessories that are affected with the 2014 models. It's gonna take time before all the vendors can catch up and make parts for our bikes.
