Yeah KRTuned makes a full system for the 07 gsxr 1000.........Kenny Roberts exhaust system......they did there work and the thing looks badass.......Rob saw one at the bike show not long ago and he said it was about a clean and good looking as it gets........suppose to make awesome power too.......its a moto gp style exhaust with a somewhat short canister and it comes in 2 available styles/colors.......they also make slip on's too but for 200 bucks more yu get the full system and that makes a lot more power and is a much better deal in my opinion.......As for a single sided full system i am almost positive there isnt one yet.....but im also positive there in the works as we speak.....
