The saw is actually up and running right now with an AM half wrap and a tuned pipe muffler. Tuned pig-rich right now but I stuck it in some wood the other day with a 3/8 50 16 inch bar on it and away she went in 18 inch year old cherry. Because the tuned pipe is designed to keep the saw within its' max torque/HP range, it does not rev as high as a dual port muffler however that is by design. Remove the copper blocking plate and put the screen back in and it turns 12.8 with chain and bar still pig-rich. Rochester, NY is nearly at sea level so whomever buys the saw will have to retune for your location.
