Why Is My Muffler Rattling?
In most cars, the muffler is installed in line with the exhaust pipe, and its job is to minimize the noise that comes from a car’s engine. Mufflers contain perforated tubes or baffled chambers that create opposing sound waves when sound waves from the engine travel into the muffler. These opposing waves partially cancel out most of the original loud noise. In most areas, hitting the road with a missing or damaged muffler is illegal. This exhaust component is required by law to keep vehicles operating at acceptable noise levels.
If you are hearing a loud sound like pieces of metal contacting each other, it usually means that something is touching the exhaust pipe. A loose bracket, rubber hanger or connector, or one that is badly corroded, can allow a muffler to rattle as the exhaust pipe bangs against another part of your vehicle when you accelerate or drive on bumpy roads, or even when you first start the car and it’s stationary and idling. When the components that hold your exhaust together fail, they can cause misalignment in the system. When this happens, a rattling noise is common. If the rattling is caused by your muffler, it will most likely originate near the rear of your vehicle.

Symptoms of a Bad or Failing Muffler
Did you know that the first internal combustion engine had a muffler installed? Although it wasn’t up to today’s standards, nor was it designed to reduce emissions or sound, the first combustion engine developed by J. J. Étienne Lenoi in 1859 had a small metal reducer on the end of the exhaust designed to reduce backfiring. Since those early days, mufflers have evolved and have become required components on any vehicle that operates on roads in the United States.
Today’s mufflers serve two functions:
To reduce exhaust system noise that is directed from exhaust ports to the exhaust pipes
To help direct exhaust gases out of the engine
A common misconception is that mufflers are also an important part of vehicle emissions. Although there are chambers located inside the muffler that help to break up particulate matter emissions, the emissions control is the duty of catalytic converters; which are installed prior to the rear muffler and can reduce dangerous chemical emissions coming from the rear of today’s combustion engines. When mufflers become worn out, they typically lose their ability to effectively “muffle” the sound of the vehicle’s exhaust.
