Most O.E. mufflers have a small drain hole on mufflers. normally in the
back, sometimes the front also, on the bottom near the seam of the
muffler.
It's perfectly normal for water to leak out there, that's why the holes
are
there. It helps get the water out of the muffler. High Humidity in the
air, more water, taking short trips and not letting the exhaust heat up
fully to take care of the water, your going to see more. A lot of times,
especially on Hot days you'll also see water leaking out the front right
of
the car also. This is because of the AC. Again it's basically the same
principle as what happens in the Exhaust. Water Va**** in the Air turning
into a solid and collecting and running out. They don't put Stainless
Exhaust pipes into cars just for the hell of it these days. The pipes
don't normally rust from the outside in, but from the inside out.
