Well made

Overall solid construction. Time for a second generation that is more refined, maybe a slimline version. Only time will tell if this aids cooling, a big problem is overheating,.

Purely awesome!

This will really wake your saw up and it sounds amazing! Especially if you want everyone to think you're running a 250cc dirt bike engine with a bar and chain on it. I put this and the foam filter kit on my brand new Stihl 661, adjusted the carburetor and went to cutting. I had made a few test cuts before adding my goodies from West Coast Saw. Night and day difference in cuts! Go ahead and order it, you won't be disappointed.
