To the point. You know when its cold out and you can see the exhaust fumes/smoke from the tips when the car is running, much like your breath when its cold out...is it normal for the exhaust to still do this some after the vehicle is shut off?

Im In NC and its our cold season, about 20-30 degrees...I let the dog out about a minute after I parked, and while watching him I caught the exhaust out of the corner of my eye...it was still slightly smoking (or whatever the term for visible fumes is) so I smelled it to see if it was just condensation melting from the hot tips, etc., and it had the regular burnt fuel smell.

Did I learn something new today, or is something wrong with the car?

I searched and didnt find anything on the topic.

That's actually steam you see. Gasoline is a hydrocarbon. So when you burn it, you mainly make CO2 and H2O. CO2 is invisible, but H2O is not.

The exhaust system is still full of hot gasses after you shut off the car, and convection will tend to pull them out the tailpipe.
