Took a short 42 mile road trip today and bought a clear title matching numbers 1980 XS650 complete except for wheels. Had another extra motor and a lot of new parts with it including this new 2 into 1 header. Part # 14711 is stamped in the megaphone. I looked on Mikes XS and didn`t see one like it. Does anyone know what this is? Tubes are 1 1/2" OD. Your help is always appreciated. Thanks.
