Description
4244 140 0606 STIHL Muffler Genuine OEM Exhaust Assembly Part
The STIHL Muffler (4244 140 0606) is a genuine OEM exhaust component designed for select STIHL backpack blowers and mistblowers, including the BR 430, BR 450, BR 450 C-EF, SR 430, and SR 450 models. This muffler is a critical engine part responsible for directing exhaust gases safely away from the cylinder while reducing noise and maintaining proper engine backpressure.
Over time, mufflers can become clogged with carbon deposits, damaged by heat stress, or cracked due to vibration and heavy professional use. A failing muffler may cause excessive exhaust noise, reduced engine performance, overheating, poor fuel efficiency, or exhaust leakage near the engine housing.
Replacing the muffler with the correct genuine STIHL OEM part restores factory exhaust flow, noise reduction, and safe engine operation without replacing the entire powerhead.
Manufactured to STIHL factory specifications, this OEM muffler ensures precise fitment, correct exhaust routing, and long-term durability under demanding commercial conditions.
