A catalytic converter or �CAT� forms part of the exhaust system of a car and reduces harmful emissions of hydrocarbons, carbon monoxide, and nitrogen oxides escaping into the atmosphere. These pieces of exhaust equipment are located underneath your vehicle and are essential for keeping your car running clean. However, they are susceptible to damage. Catalytic converters can clog, overheat, age, and even encounter physical damage from driving over bumps; so, it is essential to make sure your catalytic converter stays healthy.
