Description
Overview:
This muffler is a replacement exhaust unit for Stihl petrol chainsaws, engineered to manage exhaust flow, reduce noise, and help control emissions. Built from robust pressed steel with a heat‐resistant black finish, it is sized and ported to suit the Stihl MS 500i and MS 500i‐W. Correct back‐pressure is important for throttle response, idle stability, and overall cutting performance; a worn or cracked muffler can increase noise, leak hot gases, and reduce power. This direct‐fit unit replaces OEM No. 1147 140 0604 and matches the original mounting pattern and outlet orientation, making it suitable for routine maintenance or a like‐for‐like repair. Designed for demanding use, it withstands vibration, heat cycles, and outdoor conditions commonly encountered on site or in the field.
Key Features:
- Direct‐fit replacement for the specified MS 500i platform, replacing OEM 1147 140 0604
- Heavy‐gauge steel body with heat‐resistant coating for durability in high‐temperature use
- Restores correct exhaust back‐pressure to support power, acceleration, and stable idle
- Reduces exhaust noise to more manageable levels during cutting tasks
- Corrosion‐resistant finish helps protect against moisture, sap, and debris
- Port geometry aligned for clean exhaust routing and consistent engine performance
- Built to handle vibration and thermal cycling typical of professional chainsaw work
- Straightforward fitment using standard hand tools on compatible machines
Typical Applications:
Used to replace damaged, rusted, or noisy exhaust units on compatible Stihl chainsaws in forestry, arboriculture, landscaping, grounds maintenance, and site clearance. Suitable for routine servicing to maintain performance when cutting timber, pruning, felling, bucking, or processing firewood in demanding conditions.
