Just thought, an honourable mention must go to the bg66 stihl leaf blower. I didn’t buy it but have used one a few times. Basically, it is a bg86 stihl but low noise. They achieved this by a dirty great foam silencer on the nozzle … and a motor limited to 5800 rpm instead of 7200rpm
It did sound quieter than a normal blower, but so does a blower at half throttle haha. Bloody gutless it was.
