Louder exhaust can for FZS600

[darrsi]

I use it sometimes instead of the horn in situations where I think I have not been seen and to use the horn would sound a bit over the top.
For instance on Sunday a girl was trying to reverse park  :rolleyes and was looking over her left shoulder, her window was down and I could see that her next action was likely to be yanking straight back out so as I slowly trundled up I gave a little blib to get her attention. 
Also going around buses that have just dropped off passengers ( as well as giving a wide birth )

But you're on about avoiding potential accidents, whereas just revving the nuts off the engine just to say "Here I come, get out of my way" comes across as rather arrogant.
