I don't know if I could silence the big 800 too much... it sounds so good stock... not too loud, not too soft, just right.

Based on what I've seen online of the silencer kit, plus the look of the rack frame on the back of your new toy, I think you've probably got the best machine to hang it on. Having/making a good spot to hang one of those where it wouldn't be blocking lights and just generally in the way would seem to be the biggest challenge.
