Water in mufflers?
I just installed two new mufflers on my Corvette. I once was told by a friend that you should drill a small hole at the bottom most part of the end of the muffler to let water drain out. Anybody ever hear about something like that?

That is a good idea if you make a lot of short runs with your car that never let the exhaust get fully hot. If you make long runs the exhaust gets hot enought to evaporate any condensation.

I had a '90 Plymouth Voyager that had a small hole in the resonator & muffler. I don't know if that was factory or if the previous owner did it. Neither hole ever rusted bigger, but the muffler still rusted in another spot.
I agree that it shouldn't be a problem unless you typically make short runs that don't give the system time enough to heat up.

The replacement muffler for a relatives Acura had a small drain hole in it. My mother doesn't drive her BMW hard enough. I take it out for the occasional "excercise" session, once I actually heard water boiling in the muffler. We already had to replace that muffler, rotted from the inside out.

Thanks everyone, I wondered as the two mufflers on my 79 point down on the inlet side and i see water blowing out as she warms up. I'll drill two small holes in the low ends of the mufflers. :yesnod:
