Carbon fiber Remus exhaust. I THINK it will only fit the 2004-2012 BMW R1200GS and the R1200GSA. THE YEARS MIGHT BE WRONG. I can't remember if the exhaust pipe changes during that period. It could, however, fit others. I'm not sure exactly what years. The only identifying markings on the pipe are shown in the picture of the exhaust outlet. RV1 e 4 2039. Check with Remus, it may be cross compatible.
