Does a lot of water usually come out of the exhaust?

Normal...

It's just condensation. There is normally a "weep" hole in the muffler to allow the condensation trapped there to get out and minimize the rust.

A byproduct of combustion is water. With a hot exhaust you barely notice it. On a cold start you will see a lot of water vapor until the exhaust heats up. When you stop your engine, the remaining water vapor condenses inside your exhaust.
