MY STIHL 066 DUAL PORT BILLET MUFFLER

Mazarol · Feb 17, 2021

Hi everybody from Italy!
I don't like so much the ones you can find out there so, due to the fact that i'm a machinist, i decided to make my own dual port muffler for my beloved Stihl 066.
I made it from aluminium billet CNC machined. This is the result.

The saw now has more torque and an aggressive sound

What do you think?
I'd like to know your opinion because here in Italy it's a bit unusually to mod the chainsaws.

I think it looks great!! We need a video with sound!

That is a great looking mod. Consider doing some for your buddies and get some cash on the side. Buona fortuna!

Id buy one. Looks like it can take a hit or 2. I'm all about being different and unique. Haven't done much to my 066 red-eyes factory dp muffler but here's my 460 I had some fun with.

Why thank you. I'm going to tear the saw down soon, do some plastic welding on the handle, smooth everything out and paint everything. Should look like new once im done. I really like this saw for some reason. Id like to get my hands on a 461 or 462 to see the difference between all 3.
