People often ask us “What is a catalytic converter?” Well the catalytic converter is part of your vehicle’s emissions control system that converts toxic exhaust gases and pollutants to less toxic pollutants via a chemical reaction. The catalytic converter is made of precious metals that are a component of the chemical reaction. Most manufacturers warrant their converters for 8 years and 80,000 miles. Proper engine maintenance will extend the useful life of the catalytic converter.
