Exhaust Muffler for Husqvarna 357 and 359
This replacement muffler fits Husqvarna 357, 357XP, 359 and 359EPA chainsaws. It replaces OEM parts 503917601 and 725536855. The package includes the muffler and two M6 bolts for installation. It is designed for two-stroke, single-cylinder petrol engines.
Simple bolt-on installation with supplied hardware
The muffler attaches directly to the engine using the two included M6 bolts. No specialised tools are required beyond basic wrenches or sockets. Common issues include stripped bolt threads on older saws and carbon build-up on the mating surface that can prevent a proper seal. Ensure the gasket surface is clean before fitting.
Verify your exact chainsaw model before ordering
Confirm the model number on your saw matches 357, 357XP, 359 or 359EPA exactly. This part will not fit other Husqvarna models or different brands. Check the condition of the cylinder exhaust port and existing gasket; a damaged port or missing gasket will cause leaks. Buyers needing a catalytic converter or spark-arrestor screen integrated into the muffler should look elsewhere.

The package contains one exhaust muffler and two M6 muffler bolts; you will need to provide your own gasket and standard hand tools for installation.

The M2415 muffler is listed for the 357, 357XP, 359 and 359EPA models and replaces OEM numbers 503917601 and 725536855, so it fits the 359EPA directly.
