Related Repair Advice

  • Catalytic converters are vehicle-specific parts. We recommend using a high quality new part, which is required by emissions control programs in many states.
  • It is very important to have the shop identify why the catalytic converter failed. Failure is almost always due to another problem, which if not resolved, will quickly ruin a new catalytic converter.
