Description
Overview:
This muffler/exhaust gasket is a Genuine Stihl part designed to seal the exhaust joint on professional and vintage chainsaws. Made from heat‐resistant gasket material, it sits between the cylinder outlet and the muffler to prevent gas leaks, maintain correct back pressure, and protect nearby components from hot blow‐by. It is engineered for a precise fit on the Stihl 090 and 090G, ensuring reliable performance under tough cutting conditions. Correct sealing helps preserve power, throttle response, and tuning stability, as well as reducing noise and soot build‐up around the port. Supplied to OEM specification under part number 1106 149 0600, this gasket is a direct replacement suitable for routine maintenance, rebuilds, and exhaust refits on these large‐capacity two‐stroke saws.
