Does is it drip only when running (mostly on start up) or is is dripping all the time? If only when running then it is condensation, if all the time I would think a blown head gasket.

The hot exhaust is hitting the cooler pipes causing condensation which builds up for a little while until the pipes are hot. If you system is sealed is usually comes out the end of the tail pipes as steam and maybe some water.

It is normal. You drive in to your garage with hot exhaust, as the exhaust system cools moisture in the air and exhaust gas condenses out into your mufflers and exhaust pipes. When you start the car up the moisture is blown out the exhaust pipes.
This moisture is what usually rusts out mild steel exhaust systems, and is why all the car makers went to SS exhaust systems a few years back.

I agree with everyone else. Nothing to worry about. This happens on all cars. Look at your other cars when you first start them. They will do it too. Maybe you just haven`t noticed it yet. :cool:

That is entirely normal. Here is a drain hole on my 2001 Implala muffler that allows the condensation to drain out.
