It’s also normal in very cold weather.
Your engine actually makes water vapor. The hydrogen molecules in the hydrocarbon (gasoline) bond with oxygen atoms and form H2O… water. The carbon molecules bond with teh osyb\gen to form CO and CO2. Since gasoline is 50% hydrogen, the system makes more water than you’d think.
When the exhaust system is cold, the water vapor being carried out by the exhaust condenses on the inside of the pipes and drips out the tail pipe end. When the ambient air is cold, it can also condense around particulates in the air as it exits the pipe and form vapor clouds. It’s exactly the same process that causes jet aircraft to leave vapor clouds.
I looked at the video and it appears to me to be perfectly normal water vapor condensing in cold air. On really cold days these clouds can get downright large, even after a long drive. You can even see the clouds following cars down the highway as if they were attached to the tailpipe. It’s common in NH in really cold weather… and was an every day thing in North Dakota where it stays bone-cold all winter.
