As people have said, cars drip water like air conditioners drip water.
If your car is dripping something other than water you should get it looked at by a mechanic. Or at least someone who knows more about cars than you or I do.
But in most cases those other drips (oil, power steering fluid, coolant, brake fluid, window washer fluid, gasoline, Coke from a burst bottle you forgot in the hot sun) would be coming from another part of the car, not out the exhaust pipe.
