Exhaust tip smokes after car is turned off?

Mine does that sometimes if it's cold out. I think it's just condensation/steam. Unless you're running a brand-spankin' new exhaust, and if the smoke is coming from the surface of the pipe, in which case it's probably just that WD-40 type of oil they sometimes put on exhaust parts before shipping to help prevent corrosion while it's sitting in the warehouse or going through the mail. (My whole exhaust was smoking like mad for a couple of hours after I first bolted it all up.)

It's nothing to really be worried about, unless you smell antifreeze in there (which would probably indicate a leaky head gasket).

If it is fuel injected you may have a leaking injector that drips into the motor when the car is off. That will make it smoke because of the heat of the motor.
