TS700/TS800 Chainsaw Muffler Assembly with Screw & Washer
OEM-Spec Exhaust Silencer for Stihl TS700 & TS800 Cut-Off Saws
This muffler assembly is a direct replacement for the exhaust system on Stihl TS700 and TS800 cut-off saws, designed to manage noise and exhaust flow while standing up to demanding site conditions . The muffler channels hot gases safely away from the operator, helps maintain correct engine back pressure, and reduces overall noise output during concrete, masonry, and asphalt cutting operations. A failing muffler can cause excessive noise, reduced engine performance, or hot gas leakage that damages surrounding components. Replacing the complete assembly with OEM-spec components restores proper exhaust management, supports starting and throttle response, and ensures reliable cutting performance in construction, landscaping, and groundworks applications. The assembly includes the muffler body with a heat-resistant protective finish, mounting gaskets, and the required screws and washers for secure installation.
Technical Profiles & Materials
OEM-Spec Muffler Assembly – This is a genuine Stihl OEM muffler (OEM 4224 140 0605) for consistent performance and fitment . Engineered specifically for Stihl TS700 and TS800 cut-off saws, it is built to withstand the vibration, dust, and heat typical of construction and demolition environments. The muffler features a robust steel body with corrosion-resistant coating suited to both wet and dry cutting conditions . The precision-formed mounting points ensure reliable alignment and sealing when installed with the correct gasket.
Exhaust Gasket Included – The muffler assembly includes the essential exhaust gasket (OEM 4224 149 0600), a heat-resistant sealing component that fits between the cylinder exhaust port and the muffler . This gasket prevents hot gas leakage, maintains correct back pressure, and protects nearby components from heat and soot. The exact cut-out and fixing holes match the TS700/TS800 exhaust flange for a precise, leak-free seal . The gasket should be renewed whenever the muffler is removed during servicing .
Mounting Screws and Washers – The assembly includes OEM-spec spline screws (9022-371-1020) compatible with most Stihl cut-off saws including TS700 and TS800 . The screws are designed for the high-vibration environment of disc cutters, ensuring the muffler remains securely attached. The mounting washers help distribute clamping force evenly across the muffler flange, preventing distortion and maintaining seal integrity .

Products Application
TS700 & TS800 Cut-Off Saw Exhaust Repair
Direct replacement when the original muffler becomes damaged, corroded, or blocked by carbon buildup. A damaged muffler causes excessive noise, reduced engine performance, and potential safety hazards from hot gas leakage. This OEM-spec assembly restores proper exhaust management and ensures smooth running during concrete, masonry, and asphalt cutting tasks on building sites, roadworks, utilities, and demolition projects .
Gasket Replacement & Leak Prevention
The high-temperature exhaust gasket is essential for preventing blow-by and leakage at the cylinder exhaust port . The workshop manual specifies that the muffler is removed during cylinder servicing, and the gasket must always be renewed upon reassembly . A faulty gasket causes loss of back pressure, leading to poor throttle response and reduced cutting power. Using the correct OEM gasket ensures an accurate fit that matches the original bolt pattern and port shape .
Full Exhaust System Restoration
For contractors, hire fleets, and professional workshops, the complete muffler assembly provides all necessary components for a full exhaust system service in one package. The muffler, gasket, and mounting hardware are all supplied as a coordinated assembly . Regular replacement of the muffler assembly prevents exhaust leaks and ensures the saw maintains correct engine performance for reliable daily operations in landscaping, groundworks, and construction .
