Keep your saw running cooler and increase cutting speed. Muffler contains no spark arrestors. This is a max flow muffler for 357XP and 359. Very good for ported or high performance based saws.
  I offer this in a large single port version that is great for non ported saws. 
  International shipping to many countries. No returns. 
  Please see my other items.
  I have been producing and selling performance based high flow mufflers since 2018.
  If any of MY mufflers fail due to my workmanship, I will repair or replace the muffler free of charge to the original purchaser. Buyer pays one way return shipping only.
  Thanks for your interest support.
