A chainsaw is a powerful tool for all types of outdoor projects, from trimming trees and cutting firewood to clearing brush and felling small trees. It can be noisy, however, so having a muffler installed on your saw is important for both your safety and the comfort of others in the area. If you want to save some money and experience the satisfaction of creating your own chainsaw muffler, you can do so relatively easily with a few common tools.


  1. Remove the old muffler from the chainsaw using a wrench. It is located at the end of the exhaust pipe.
  2. Measure and cut a piece of sheet metal for the new muffler, about 5 inches in diameter with twice as much length as width. Make sure to account for extra space if you are planning on adding a deflector screen or any other components.
  3. Place the sheet metal around one end of an exhaust pipe and bend it into shape around that end, leaving enough room for any additional components you plan on adding. Secure it in place by drilling holes in both sides and inserting screws or bolts through them to hold it tight against the exhaust pipe itself.
  4. Attach screen to the other end of the muffler, if desired. This will help redirect some of the exhaust gases away from the user and reduce noise levels.
  5. Reattach the new muffler to the chainsaw using a wrench and secure it in place with screws or bolts.
