NOt sure why dipping your exhaust in water would be so harmful (unless salt water). The outside certainly gets wet every time it rains and if the pipe is submerged with engine running I assume not much water is making it too far up against the pressure of the exiting exhaust. Of course, turning the car off and the water running in to the muffler and headers? I'm sure plenty of condensation hangs out in there in colder months and any water would quickly be burned off....no?
