Thanks for posting your pics. I got my 05 919 used a few weeks ago and it had a windscreen on it. After seeing your pics I remembered how damn hot these bikes are with out a screen, so I went out and stripped it off and I am fully naked now.
It's sort of crappy, but here is a quick mp3 file of the exhaust. The first part is about 15 feet away with the exhaust pointing away from me. The second part is about 10 feet away with the exhaust facing me.
