Go for it. They look great and sound great. Any exhaust will get damaged if they get knocked over so I wouldn't worry about that.
He Man - I had high mounts on my 695 which was knocked over twice and both times the pipes held up pretty well. Only scratches no major punctures or dents. One time the pipe was even supporting part of the bikes weight as the can was resting on the curb and hte rest of the bike was on the street.
