Rust can also form internally due to condensation from normal day-to-day use. The droplets are a byproduct of the condensation that forms when the exhaust is hot and cools down. A steady stream of water coming out of the muffler can be an indicator of excessive rust or rot.
When your car gets very loud, it can also start to feel a little sluggish. Or, excessive rust may have created a hole in the part. Any vibrations you hear, or rattling you feel, underneath the car can also indicate a faulty muffler. You may notice that your car is running hotter than normal, or see a decrease in fuel efficiency.
This could be caused by the internal chambers of the muffler rusting apart. If that happens, exhaust gases cannot escape properly. You could even get a ticket for excessive noise!

Sound is a pressure wave formed from pulses of alternating high and low air pressure. These pulses makes their way through the air at -- you guessed it -- the speed of sound. In an engine , pulses are created when an exhaust valve opens and a burst of high-pressure gas suddenly enters the exhaust system.
The molecules in this gas collide with the lower-pressure molecules in the pipe, causing them to stack up on each other. They in turn stack up on the molecules a little further down the pipe, leaving an area of low pressure behind. In this way, the sound wave makes its way down the pipe much faster than the actual gases do. When these pressure pulses reach your ear , the eardrum vibrates back and forth.
Your brain interprets this motion as sound. Two main characteristics of the wave determine how we perceive the sound:. However, plenty of muffler designs are out there, so you should have no problem finding one that suits your lifestyle.
If your ordinarily quiet ride suddenly becomes atrociously loud, then you should consider having your muffler examined, as a replacement may be in order.
