Additional information

This engine muffler baffle installs inside the muffler and helps control how exhaust gases move through the muffler chamber. Part number 951-11181 supports proper exhaust flow while helping reduce excessive engine noise during operation.

If the baffle cracks, loosens, or breaks apart, the engine may sound louder than normal or develop a rattling noise from inside the muffler. In some cases, exhaust flow may become restricted or uneven, which can affect engine performance.

Disconnect the spark plug wire before starting the repair to prevent accidental engine startup. Allow the engine and muffler to cool completely before handling exhaust components, and wear work gloves to protect against sharp edges.
