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.
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.
Egan Straight Shot Performance Chainsaw Muffler 660/066/650 and later model 064
Installed the straight shot muffler and the add-on deflector on a brand new farmmac 660. Everything fit perfectly. Looks really good, sounds really good. Its loud. Didnt have but a few mins run time on the saw with the stock muffler so I cant really speak on the performance gains. Only issue that I can see so far is after installing the straight shot its seems to have increased the vibration in the saw but its also still brand new so maybe that will work itself out once the saw gets broken in and I get the carb tuned just right. Also purchased a set of the felling dawgs and they look awesome and are definitely more heavy duty than the ones that came with the saw. All in all, im happy with the products I purchased. Shipping was fast. Order was correct. Not much more I could ask for.
Amazing how well it works. Like night and day difference
