Bolt on more power with an Egan Performance “straight shot” muffler to your Stihl 381 chainsaw for an immediate increase in power and throttle response and a reduction of engine temperatures.
Please note: This cover has four mounting holes and is a direct bolt on for the 381. It can also be used for 038/380/382 if an aftermarket two-piece muffler is used. Please look closely at your saw before ordering. If your muffler doesn't have 4 mounting holes, then this cover won't work.
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.
my dumbass didn’t read that it NEEDS the 4 bolt backing for a 038 AV. Jason got back to me ASAP and let me know what to do & fixed up quick. This old saw is growlin’
Bought one for my 026 and one for my 038 Magnum. Simple to install and really opened the saws up. Couldn’t be more pleased with the results.
I put this on my Neotec 872i. Sounds great and the throttle response is phenomenal. Well built as well.
This thing is awesome. Super thick plate steel, great welds, removeable mesh screen. Comes with 2 longer screws for the top holes since the plate steel is like 1/4" thick. You could knock someone out with this thing. The sound is mean and the saw seems way more snappy now. Great mod to add to the saw.
