WESTCOAST SAW BARK BOX FITS STIHL 066 MS660

We've teamed up with WESTCOAST SAW and are now stocking the Bark Box muffler covers!  Super heavy duty and field tested.  

With a name like "Bark Box™," Westcoast Saw lets you know exactly what you're getting! This muffler cover took a year to perfect with lots of testing involved. It is constructed out of stainless steel and hand tig welded that holds up to abuse. It also has a spark arrester built in. 

Expect cooler running temperatures, a rowdy sound, and 6-10% horsepower gain. 

Bark Boxes are compatible with 2-piece muffler covers only.
