Yes, it is M18 (18mm thread). Or maybe it's easier to say, it is the same size as Bosch narrowband, or wideband O2 sensors. That is a standard size for O2 sensors.
It is a generic narrow-band, heated, and film-type oxygen sensor. Bosch calls this tech LSF sensors. It's the same tech as the millions O2 sensors used on today's cars.
BTW, it should not to be installed on the "muffler", but should be installed 3-5
" downstream of the exhaust port.
EDIT: 3-5".
