Briggs & Stratton 591018 Muffler

The Briggs & Stratton 591018 Muffler helps direct engine exhaust gases away from the exhaust outlet while reducing operating noise. It forms part of the engine exhaust system, allowing gases to pass through internal chambers that help control sound during operation. Proper muffler condition supports effective exhaust flow and quieter engine performance. Replacing a damaged or corroded muffler can help restore exhaust system function and support routine engine maintenance.
