Description
Overview:
This is a Genuine Stihl muffler/exhaust assembly for professional petrol chainsaws. Built from pressed steel with a heat‐resistant, corrosion‐resistant finish, it manages engine noise and guides hot exhaust gases safely away from the operator. Correct back pressure helps the engine run smoothly and maintain performance. Designed as a direct replacement for worn or damaged units, it is suitable for the Stihl MS 441 and MS 441 C. Supplied to the original equipment specification under MPN 1138 140 0655 (11381400655), it fits the factory mounting points and aligns with the original exhaust outlet position. Using a genuine OEM muffler protects reliability, reduces vibration from a failing exhaust, and supports the longevity of surrounding components such as covers, brackets, and anti‐vibration mounts.
