About Stihl Mufflers:

The muffler on your Stihl chainsaw, cut off saw,
trimmer or other equipment plays a number of
important roles. First and most obvious is the reduction
of sound from the engine. Second is to capture the
extremely hot gases released through the cylinder
exhaust port after combustion. These gases can not
only cause serious burns, they can also start fires if
exposed to saw dust or other combustibles. For this
reason a seriously rusted or damaged muffler on any
Stihl equipment should always be replaced. The third
important role is in engine performance.

The muffler provides back pressure to the engine
exhaust and as a result greatly affects performance by
controlling the flow rate of exhaust gases. A common
modification performed on Stihl chainsaws is called
muffler porting. This involves drilling a hole, or holes,
into the muffler to increase the exhaust gas flow rate.
By some estimates modifying a Stihl chainsaw through
muffler porting can increase power up to 20% however
muffler porting can also reduce power if performed
improperly. One rule of thumb suggests that the total
hole size added to the muffler should never be greater
than 80% of the size of the exhaust hole in the cylinder
head. A spark arresting screen should also be fastened
over to new hole because porting affects the mufflers
ability to catch any pieces of hot carbon released
through the exhaust. One common procedure is to weld
a short length of pipe over the drilled hole in the muffler
and than attach the screen to end of the pipe. The
addition of the pipe also allows for further control of
exhaust gas direction by placing a curve in the pipe.
Before modifying a Stihl chainsaw by muffler porting
one should also consider that this can void the
manufacturer’s warranty.
