condensation.....happens when your AC is on.

Humidity. Water in the air condenses when the exhaust system cools and it pools in the muffler. If you live in a perpetually humid environment it's best if you drive far enough every day to boil it all out or the muffler will eventually rust out.

OK, slightly different interpretation than Rusty .

Moisture is one of the by-products of combustion. So when you start your car, warm moisture is one of the products coming out of your tailpipe. Since your exhaust system is cold when you start your car, the moisture condenses on the surfaces of your exhaust system, collects in the muffler and that is what you see drbbling out the tail pipe. The condensation stops as soon as your exhaust system has sufficiently warmed up.

And as Rusty said, this is why exhaust systems on cars that are mostly driven on short trips fail before cars mostly driven further (like 9 miles or more). The condensation doesn't have a chance to be blown out/dryed out in the muffler, and the clollected water will corrode the muffler from inside out.
