Westcoast Saw Bark Box - MS660

This is a stainless steel high flow muffler for improved exhaust gas flow out of your saw. Integrated spark arrestor screen included in the muffler cover.
It can add power, reduce cylinder head temperatures during operation and sounds like a hot rod!
This bolts on directly to your G660, Bulletproof 660 or MS660/066 muffler.
Hand made in the USA.
