Why are car mufflers loud?

The word “muffler” makes it seem like it should, you know, muffle the sound of a car… but every muffler I hear is obnoxiously loud. What gives?

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.

That reminds me of a joke; What do Hawaiian shirts and modified exhaust systems have in common? They're both designed to be "LOUD."

a muffler's job is to do what its name implies — muffle the noise made by your exhaust. But when a muffler wears out and no longer does its job, the the result is loud noise.

They're sold and tuned (as per customer preference) to sound like a nusaince.

If the term you are looking for is Harley-Davidson-Mufflers, they were brought onto the market between 1941-1949. They range in price between $50 and $500 depending on how large and loud you want them to be.
