I bought a new Racefit exhaust for my CBR so am looking to sell the one that is currently on it. I haven't removed it from the bike yet but will this evening. I don't know much about the slip-on only that it says its a GPR and that it came with the bike when i bought it. I checked the GPR website and cant find a matching photo and I noticed that the logo appears to be different. I can only assume its a Chinese replica and as such am open to offers. It might make a cheap spare for somebody with a track bike. It is in good operational condition with no visible damage and comes with the link pipe and springs and hanger bolt etc. My bike has been running fine with it fitted and the sound quality is good. Anybody interested?
