A friend of mine ordered a pair of carbon fiber slip ons for his 2006 zx-10r and they were on back order until july. He has had them on the bike for the last few months of riding and says they are in perfect condition. They are too quiet for him and he wants a kenny roberts exhaust. He said he paid $1000 for the whole set up (both cans) and wants to get $800 for them. They will fit 2006-2007 any interest Pm me or post an email and I can get more info or give you a phone number.
