You can just drill a hole in it and keep making it bigger till it sounds like a Harley then you have it.

My saw is about a 2003 model. It had the restricted muffler on it. I bought some 066 parts on ebay and it had an old style in it . Put on the front half of it and then it ran real good. Makes a lot of difference in the power. If I couldnt find a muffler I would just drill a hole in it. About 1/2 in. in size. Thats as long as I wasnt cutting where it could start a fire. The old saws didnt even have mufflers , they shot straight out the front. I have seen embers on the log after cutting it with the old Mono. Good luck with the 066 shes a good saw. Mine cuts about 10 cord of firewood each year. Harold
