The Stihl MS261 Muffler 1141 140 0631 is a genuine STIHL replacement exhaust muffler designed for the MS 261 professional chainsaw range. The muffler plays an important role in directing exhaust gases away from the engine while helping to control exhaust noise and maintain the correct exhaust flow.

A damaged, corroded or blocked muffler can affect chainsaw performance, increase exhaust noise and potentially restrict the engine. Replacing a worn muffler with the correct genuine STIHL part helps restore the chainsaw’s exhaust system to the correct specification.

This is an ideal replacement part for servicing and repairing Stihl MS 261 and compatible MS 261 C variants. The STIHL parts documentation identifies 1141 140 0631 specifically as the muffler for the MS 261 series.
