Keep your saw running cooler and increase cutting speed with this muffler. Contains no spark arrestors. Rubber plug is included to close front port while not in use. 

 International shipping to many countries. 

   This muffler has been modified internally and externally to provide good exhaust flow. Don't be fooled by others that are plugged up with baffling and poor exhaust ports. Picture #3 is view from cylinder exhaust port to the piped port I added in the front. 

  I have been producing and selling performance based high flow chainsaw mufflers since 2018. 

  If any of MY mufflers fail due to my workmanship, I will repair or replace it free of charge to the original purchaser. Buyer pays one way return shipping only.

  Please look at my other items.

 Thank you for your consideration.
