Description
Overview:
This genuine Stihl muffler/exhaust is a direct replacement for selected petrol two‐stroke brushcutters, Kombi engines and handheld tools. Made from pressed steel with a heat‐resistant coating, it reduces noise, manages exhaust flow and directs hot gases safely away from the user. Correct back pressure helps maintain smooth running and power on machines such as the Stihl FS 55 and FS 55 C. Supplied under Stihl MPN 4140 140 0617 (replaces 4140 140 0609), it is suitable for preventive maintenance or when the original silencer is rusted, dented or carbon‐clogged. The factory form factor integrates with OEM mounting points for a straightforward swap using basic hand tools, restoring quiet, efficient operation for day‐to‐day trimming and clearing tasks.
