Description
Overview:
This Genuine Stihl baffle (MPN 1128 121 6900) is a precision steel insert for the exhaust/muffler assembly on Stihl professional chainsaws, including the MS 460 and 046. Its job is to manage exhaust gas flow and back pressure so the engine runs smoothly, with stable idle, strong acceleration, and reliable cutting performance under load. Built from robust, heat-resistant metal to cope with high temperatures, vibration, and carbon build-up, it restores the intended exhaust path and helps the saw maintain efficiency. As an original Stihl part, it ensures the correct fit and geometry inside the muffler without modification. A practical replacement when the original baffle becomes warped, corroded, or damaged through heavy use in forestry or landscaping work.
Key Features:
- Genuine Stihl OEM part for exact fit and reliable performance
- Controls exhaust gas path and back pressure within the muffler
- Durable steel construction for long service life in harsh conditions
- Helps maintain power output, throttle response, and fuel economy
- Supports consistent starting and idling behaviour
- Heat-resistant design stands up to prolonged high-temperature operation
- Straightforward like-for-like replacement using the original muffler housing
- Suitable for professional and demanding DIY applications
Typical Applications:
Used to replace a worn or damaged exhaust baffle in working chainsaws to restore correct exhaust flow and engine characteristics. Ideal for saws used in felling, bucking, site clearance, storm clean-up, and general forestry or landscaping tasks where sustained cutting can stress the exhaust system.
