Factory 2nd exhaust
 

I was just looking for some spares for my other bike and stumbled on this exhaust can. It is a factory 2nd, but if someone is looking for cheapish race can, it might be of interset to them. I have no idea what bsm exhausts are like but it might be just what one of you are looking for
