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 Duffy's Auto Service, in Saint Paul Park at 651-459-9052 today.
