Good To Know
Q: Will this muffler fit both Kohler Command and Courage engines? A: Yes, the CH18-CH25 (Command) and CH620-740 (Courage) families share similar exhaust layouts, so this right-side muffler is compatible with both series.
Q: Is a gasket included in the box? A: The muffler ships as a standalone unit; you can reuse the existing gasket or purchase a new one separately for a secure seal.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
