New car owners struggle with the question, “What are the symptoms of a bad muffler?” Knowing these signs informs you when to replace or fix faulty mufflers and avoid high repair costs, and get a longer engine lifespan.

  1. Noisy Muffler: The clearest answer to the question "What are the symptoms of a bad muffler?" is loud roaring noises from the muffler. A muffler can get damaged from debris when driving in bad road conditions. You might notice thumping, clanking, and stifling noises in your exhaust system if the muffler is bad. However, it is worth noting whether your state prohibits modifying exhaust systems before getting heavy fines.
  2. Decreased Fuel Efficiency: A bad muffler restricts your exhaust’s flow, which in turn stresses your engine. As a result, the engine's performance decreases and the fuel efficiency drops. There might be an issue with your muffler if you observe a drop in the mileage per gallon of fuel.
  3. Foul Smell: A new muffler filters gases and fumes from the exhaust and prevents them from being released to the car. However, the leaks in a bad muffler make it impossible to filter these gases, thereby releasing them into the car. New mufflers are necessary, as these gases have serious health effects.
  4. Rusting: Extensive rusting is an indication of a faulty muffler. Short trips do not allow exhaust systems to heat up enough, leading to the formation of water deposits. Water in the exhaust reacts with oxygen, causing it to rust.
