Bark box is worth it!
Bought the bark box on a whim and it’s not as loud as some think with ear muffs on and I feel the saw runs smoother and it looks good! I’d buy again with ease and it seems heavy duty plus fast shipping from the west coast to the east coast.

I just ordered a second one. I put this one on my 400cm and ordered another for my 362cm. It really woke the saw up. You may want double ear protection. It is loud.

Great Bark for the Buck!
I think I'm up to 5 of these things now and love every one. They transform a saw on a few levels, the main being getting heat away from the cylinder. The added bonus is the crisp throaty sound and added torque they provide.
I'm a production faller by trade, so I'm not interested in fluff. The WCS products I use always impress.
