Description
Overview:
This exhaust gasket is a genuine Briggs & Stratton replacement part designed to seal the joint between the exhaust port and muffler on 16 HP (approx. 11.9 kW) Series engines. Made from heat-resistant gasket material engineered for exhaust temperatures and vibration, it restores a gas-tight seal to prevent leaks, loss of power, and unwanted fumes. It is an OEM match for engines such as 305440-3052-G1 and 305442-0527-F1 and is suitable for many similar 16 HP twin-cylinder and single-cylinder applications across lawn and garden machinery and small plant. Using the correct gasket helps maintain back pressure, keeps noise levels stable, and protects nearby components from hot escaping gases. Part reference: Briggs & Stratton 691613.
