Why do mufflers corrode?
One of the big reasons that mufflers start to rust is because of the moisture that gets trapped inside of them, causing it to rust from the inside out. If you only drive your car a short distance, it never gets hot enough to completely evaporate the moisture inside the muffler.
How do you fix a corroded exhaust?
