Delivers 19.25% additional torque, giving the Stihl MS261 stronger pull under load and measurably improved real-world cutting performance, helping to maintain chain speed when running longer bars or cutting in dense hardwood.
Dyno testing showed a 19.25% increase in torque and a 12.93% increase in horsepower on a completely stock MS261 with no other modifications. This added torque is delivered across the working powerband, allowing the saw to hold RPM through the cut and recover faster under load.
Engineered for users who care about usable power, this performance muffler delivers faster cuts, less bog in hardwood, and more consistent performance in demanding conditions. Improved exhaust flow also helps the engine shed heat more efficiently while providing a sharper, more immediate throttle response during acceleration and cut entry.
The optimized exhaust design also produces a deeper, more defined exhaust note that reflects the added torque and throttle response, without sounding harsh or uncontrolled.
Torque Gain: up to 19.25%
Horsepower Gain: 12.93%
Tested on a stock MS261 with no additional modifications
CNC-machined from aircraft-grade aluminum for strength and durability
Optimized exhaust passage design for improved cooling
Faster, more responsive throttle feel
Integrated spark arrestor for added safety
OEM four-point mounting using factory screws for maximum stability
Sleek 3-piece design that complements the MS261’s streamlined look
American-made quality
🛠️ Lifetime Warranty — built for long-term reliability
Detailed installation instructions included, making this upgrade approachable even for users new to chainsaw modifications
We’re here to help — if you have questions during installation or setup, support is available to ensure a smooth, confident install
Whether you’re a professional arborist or a serious firewood cutter, this bolt-on upgrade is designed to make your MS261 pull harder where it actually works. The result is a saw that cuts faster, maintains RPM better under load, runs cooler, and feels more responsive throughout the cut — not just on a dyno chart.
Compatible with all variations of the Stihl MS261.
