• Exhaust leak: Signs of an exhaust leak include higher noise levels and reduced engine performance. You might also notice a burning smell, visible smoke, or steam, due to gases escaping from the system before they reach the tailpipe.
• Catalytic converter failure: If this part begins to fail, you might notice reduced performance or your car might fail an emissions test. You might also smell a ‘rotten egg’ smell due to the catalytic converter not converting the hydrogen sulfide in the exhaust gasses.
• Muffler damage: This can cause reduced fuel efficiency, decreased engine performance, and excessive noise.You might also notice physical damage to the muffler. An extremely damaged muffler can even cause exhaust fumes to enter the cabin of the vehicle, which is incredibly dangerous.
• Exhaust pipe corrosion: This is often noticed first visually, but if left untreated, it can cause the pipe to fall apart. Extensive rust may cause the exhaust pipe to sag, leading to loud noises as it impacts bumps and road debris.
• Oxygen sensor malfunction: When your oxygen sensor fails, your engine can run rich or lean, resulting in backfires and reduced efficiency. You may also notice your car idling roughly or even stalling due to the uneven distribution of fuel. A faulty oxygen sensor can also trigger the check engine light, which always necessitates a trip to the mechanic.
