I have recently bought a used 660 on ebay. I used it on a job for the first time today, has a 20" bar on it and it is scary. I will be putting a 25" bar on it and really need a 28" or 32" for felling cuts. It does have a large port on the muffler, not use to that, just used factory saws with two small openings. Should I change the muffler, it sounds louder than our 650 at work, but think I will leave it for now.
