Information
What does a muffler do?
A muffler reduces noise from the engine and is typically installed along the exhaust pipe of a vehicle. The tubes and chambers of a muffler reflect sound waves produced by the engine. By adding two opposite sound waves together, the waves cancel each other out, thereby creating less sound.
Why is my muffler making a loud noise?
If the muffler is making a loud noise, like a hissing or popping sound, the muffler is probably worn out and needs to be replaced. Lots of short trips during cold weather could leave condensation in the exhaust system and cause corrosion. Also, over time small holes and exhaust leaks can develop, or cracked or damaged pipes can occur. Even very small amounts of carbon monoxide that can escape into the passenger compartment from leaks are extremely dangerous.
What are my options?
A vehicle can be taken to an auto repair shop. An owner may also be able to diagnose what is causing the problem, but caution is advised since carbon monoxide is dangerous. Some automotive websites offer free DIY diagnostic or repair instructions, and other sites advertise services and sell parts. There are service manuals and how-to books that can also be purchased online.
