The catalytic converter is a major component of the exhaust system in your car, truck, or SUV. It converts unhealthy pollutants into less harmful emissions that emanate from your car’s exhaust pipe. If your engine loses performance, you hear rattling noises, or your check engine light comes on, your catalytic converter might need to be replaced. Your vehicle’s entire exhaust system can suffer because of a problem with the catalytic converter. If you suspect your catalytic converter may need replacing, or if your catalytic converter is missing, call Greg's Champion Auto, in Mankato at 507-344-3300 today.
