Hi there,

Some mufflers do have a small drain hole, H2o is a by product of combustion and when the engine &exhaust is cool the water will condense and lie in the pipes and muffler, typical is a 5 min round trip to the store, this hole will help the water drain away as if it sits there, it will prematurely start to rust out the exhaust.
