I recently purchased a blue/white/black 2008 r6. Love it no complaints. At my first oil change i had motul oil, yoshi bar ends, gytr frame sliders, and had a leo vince sbk factory evo 2 carbon fiber w/ carbon fiber end cap put on pricey for a slip on a little over $600. I took out the silencer/ db killer and it isn't necessarily much louder than stock, but deeper and more throaty sounding. Anyone looking for a good slip on i suggest Leo Vince great exhaust. Sounds great when u really rev the bike up in the rpms.
