Has anyone used or have a silencer on their 570? I have got an ETX but I looked it up and as far as I can tell the 14 and 15 570 both share the same exhaust as the new ETX model. I know these machines are already pretty damn quiet, but Id really like to cut some more out for around hunting season. The ones Ive seen basically fit across the rear of the machine and attach to the stock exhaust.
