[QUOTE=markeb01;6742520]Condensation in a muffler on start up is normal, as the moisture in the outside air is drawn into the pipe and "rains" inside. The best method for long muffler life is driving the vehicle long enough to dry them out every time the engine is started. On a daily driver with a short commute this may be impractical.QUOTE]


Actually, condensation (water) is a by-product of the combustion process. It is not "drawn in" (well, it probably is to a degree but the real culprit is combustion). Even in Arizona you see water coming out of tailpipes in the morning when everyone is just hitting the road. Same issue with condensation in the engine. The only viable alternative is to drive until everything heats up enough to evaporate it (oil and muffler). I run mine as a daily driver with a very short commute and it is an issue. But I don’t think extra holes in the muffler is the answer……
