Description

Overview:
This Muffler/Exhaust is a genuine Stihl replacement part for professional clearing saws, designed to restore safe, quiet and efficient operation. Built from durable pressed steel with a heat‐resistant black finish, it manages exhaust flow to maintain correct back pressure, reduces noise, and directs hot gases away from the user. It is engineered specifically for Stihl FS400 and FS450 machines, giving a precise fit to the cylinder and mounting points for reliable sealing. As an OEM component (MPN/OEM No. 4128 140 0601), it matches the original specification and is suitable for frequent, heavy‐duty use in demanding environments. Replacing a worn or damaged exhaust helps protect engine performance, reduce vibration and heat build‐up, and extend the service life of your clearing saw.
