Swisher 14391 V-Twin Muffler Assembly

This V-Twin muffler assembly serves as a direct replacement for Briggs & Stratton M44 series engines utilized in outdoor power equipment such as zero-turn mowers and garden tractors. The component attenuates exhaust noise through internal baffle geometry while managing backpressure for the 90-degree V-Twin cylinder configuration. Constructed from aluminized steel for corrosion resistance, the unit features a single inlet configuration specific to the M44 engine exhaust port layout. It replaces Swisher OEM part number 14391 and corresponds to Briggs & Stratton V-Twin muffler applications. Verification of the engine model number is recommended prior to installation to ensure correct fitment.
