Bolt on more power with an Egan Performance “straight shot” muffler to your Stihl 661 chainsaw for an immediate increase in power and throttle response and a reduction of engine temperatures.
Made in the USA from 10 gauge 304 stainless steel, with USFS approved spark arrestor.
We now also offer the option of an add-on Straight Shot Deflector Extension. Please see that products description for additional information.
Upon installation, the saw will need recalibrated or carb will need retuned.
The straight shot is great, noticeably great performance balance, also all around
This muffler really woke the saw up, the build quality was top notch, everything fit properly and was easy to install. The saw sounds amazing, it does make the saw louder but isn’t unmanageable.
Perfect fit and made a noticeable power difference. Revs quicker
Definitive difference in throttle response. The sound just make me think America
Quality exhaust for pro timber fallers. Best on the market
