I have a topic just for fun.  My friend believes that a car exhaust system rusts (and fails) mostly from the outside in.  I think it rusts from the inside out and then fails.  As a result, he paints his exhaust system with high temperature paint to inhibit corrosion.

Any ideas, comments??

Your right. Corrodes from inside out. Combustion gasses going through the cat converter turn into CO, water, Co2, and some others. Put them all together inside your muffler and its a pretty nasty soup. Most good quality mufflers are stainless or at least galvanized so painting wont do a thing.
