Well, you only hear the loud ones. The purpose of a car muffler is to silence the car’s exhaust system—in fact, in the UK, they’re called silencers—and most are pretty successful. The loud ones are either faulty, modified to be loud, or are something called “performance mufflers,” which are designed to increase car performance and split the gap between, well, muffled and unmuffled.
So, your average muffler eliminates most of the exhaust noise by leading sound waves through sound-cancelling channels and chambers; modified and performance mufflers, on the other hand, let some of the cool sounds out.
If your muffler isn’t usually loud but starts to make noise, get that checked right away, as that could mean harmful fumes are leaking into your car.
