Hello! I have a Kohler CV22 on a Craftsman Garden Tractor with a starter side exhaust. There is a manifold that feeds this exhaust so it is a two piece system. I am looking for the Muffler but would by both if available. The diameter of the inlet is 1-1/8" (1.125'). Is this something that sounds familiar? I may be looking at old/used as the part(s) are no longer available from Sears. Maybe someone knows options or graveyard parts locations.
