With a name like "Bark Box®," Westcoast Saw™ lets you know exactly what you're getting! This muffler cover is constructed out of stainless steel and hand TIG welded. It also has a spark arrester built in. Made in the USA.
Expect cooler running temperatures, a rowdy sound, and 6-10% horsepower gain.
Installation Note: If your saw is M-tronic it will be tuned in by the third or fourth cut after installation. If your saw is non M-tronic, we recommend re-tuning after installation.
Bark Boxes are compatible with 2-piece muffler covers only.
461/440, 661 & 500i run gaskets between the 2-piece mufflers, Replacements can be found HERE
