Drilling hole in muffler to let out moisture. Have you done this?
Some time ago someone recommended creating a small hole at the bottom of a muffler to let out excess moisture. Idea was to prevent rust on the inside. Is this nonsense? Seems iffy, especially with salt getting into the inside of the muffler in the winter and making the situation worse.

The muffler on my 89 GT actually came with a weep hole in it.

Driving the car seems to push the water out, I live in Seattle and if I had a tiny hole in my muffler it would fill up while parked as that is about where the water line is in most places....

Drive the car more often and you should encounter less car issues as a whole. Once the car runs for 20 minutes the muffler should get hot enough to evapoate all the moisture that is in it.

Haha.... I knew I'd get hammered for this one. I drive my car lots, so no worries there. The root of my question was with whatever residual there might be once the engine is shut off. I guess the answer is no!
