A catalytic converter, often referred to as a "cat," is an essential component of your engine's exhaust system. This device uses catalysts to transform harmful chemicals in the exhaust gases.

What are the signs of a bad catalytic converter?

  • Check engine light
    The dashboard warning light may illuminate, indicating potential issues.
  • Decreased engine performance
    Noticeable loss of power, acceleration, or overall engine performance.
  • Poor fuel economy
    A significant drop in fuel efficiency can occur as the converter fails.
  • Excessive exhaust emissions
    Increased emissions, including a strong sulfur or rotten egg smell.
  • Rattling noises
    Unusual rattling sounds from the exhaust system, indicating internal damage.
  • Overheating
    The engine may run hotter than normal due to restricted exhaust flow.
  • Failed emissions test
    Inability to pass emissions testing due to high pollution levels.
