I need to replace the exhaust system on at least one side of my bike. The OEM muffler 18400-KBA-007 is no longer available. My research indicates that the CMX250, the Rebel250 and the CB250 nighthawk all used the same engines as the CM250C. Has anyone ever tried to install a muffler system from one of these other bikes onto the 1982 CM250C. From the diagrams it looks like the 184-KBG-010 will work. Any help would be appreciated.
