The Stihl Muffler and Exhaust Gasket is a genuine replacement part designed specifically to seal the connection between the cylinder and muffler on compatible chainsaws. Crafted from heat-resistant gasket material, this gasket compresses to form a gas-tight seal, effectively preventing exhaust leaks and maintaining proper back pressure for optimal engine performance. This gasket is suitable for medium to large Stihl chainsaws, including the MS311 and MS391 models, making it an essential component for forestry, landscaping, and farm work. It is recommended to replace the gasket whenever the muffler is removed, during exhaust maintenance, or if you observe excessive noise, fumes, or soot around the exhaust outlet.
