If you don’t want to learnhow to fix a broken muffler, it’s important that you take care of it. For starters, the muffler is needed to cancel out unwanted engine noise. This loud noise can become annoying to some and might even violate local laws.

The muffler is also used to control engine backpressure. When it works the way it was intended, the engine can perform optimally, allowing for better acceleration and efficiency.

• Excessive Engine/Exhaust Noise
  Sometimes, the first sign that something is wrong is due to a louder exhaust. Whether the pipes arecrackedor rust causes a hole, the exhaust will be louder when it is broken.
• Reduced Fuel Economy
  As the exhaust system fails to do its job, the enginehas towork harder. This added pressure creates a reduction in fuel economy, but not generally by a lot.
• Slow Acceleration
  If there is a leak in the exhaust, you might find yourself pushing harder on the pedal to make the vehicle respond. Plus, if the leak is small, you might not even hear any added noise.
• Stench Of Strong Gases
  If you smell unusual gases, it could be due to a broken exhaust. You need to have this checked right away as you don’t want dangerous gases infiltrating the cabin.
• Banging Or Knocking Sound
  If an exhaust mount or hanger has come loose, part of the system could be banging around under the car, which could lead to further damage. If the mufflerfalls down, it could also drag along the ground.
• Rust CausedByCondensation
  As condensation builds up, the muffler and tailpipes are susceptible to rust. If you allow the rust to take over, you will end up with holes in the exhaust system components.
• Engine Misfiring
  When the engine misfires, it can indicate problems with numerous systems. However, a faulty exhaust is also one that should be looked at because there could be a clog somewhere.
• Burning Smell ComingFromEngine
  From the exhaust manifold to the motor head, there is a manifold gasket. When a tear or leak occurs at this location, escaping heat can cause nearby wires or plastic components to burn and create a bad smell.
