Bolt on more power with an Egan Performance “straight shot” muffler to your Stihl 660, 066, and 650 chainsaw for an immediate increase in power and throttle response and a reduction of engine temperatures. This cover will also fit later model 064s and ms660.
Please note the difference in this model of muffler from the one for the older Stihl 064. Please review pictures closely and compare to your saw to ensure that you are ordering the correct muffler.
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 the product description for additional information.
Upon installation, the saw will need recalibrated or carb will need retuned.
Customer Reviews
Great products and even better customer service
If you crave more power, than this is the product for you! If you day dream about how you can customize just about everything you own, than this one’s for you! If the thought of grabbing third gear in a fully built 68’ Camaro right before red line gets you off, then this is for you!
BUT BEWARE!!!! This is not for the faint of heart! This is a true performance muffler that will take your thanksgiving turkey carver to the next level! You will experience torque gains that will pull more wood than Buckee the beaver on a steroid cycle! If you crave the crisp clean crack of a two stroke in the cool mornings air dogged into a big nasty log pulling like a freight train, then you came to the right place!
BUT PLEASE!!!! If you are one of those types of people who buy a performance anything and then want to complain that it’s too loud or too rowdy because it hurt your “feelings” and delicate man mittens,,,,,,,then please do not buy this! Stay with your stock muffler and just be happy. For the rest of us out there, buy this bad boy and let the sound of American freedom ring throughout the hills and neighborhoods like the days of old!
What can I say, it’s my second straight shot! Makes the saw pull harder and faster! Believe me it’s worth the investment
sounds great lot more power keep good work going thanks so much.
