i currently have the r-77 dual slip-ons on my 08 busa and i love them. Sorry, no pics right now. They were pretty pricey for just slip-ons (i think about $800), but i am totally satisfied with them. I was surprised how much louder the bike was once installed. It's not an annoying cackling tone, but has a pretty deep, mellow sound to it, which is exactly what i wanted. I installed the silencers that come with them once, and it almost sounded like stock again it was so quiet with these installed. I absolutely love the dual slip-ons and have no regrets with them
