I like nothing more than having a bike that is different and like no other. As for the exhaust, I know that removing the muffler would require remaps, testing, more remaps and even then you really have to know what to look for and keep up on. Mostly I just wanted to get rid of the weight even though it is in a low centralized place. However I was hoping that in removing the muffler it would open up a little performance and maybe some sound as well.
