The vehicle in your driveway symbolizes the best in class compared to all the other cars, trucks, and SUVs on the road today. Your Cadillac dealership isn't the only place to locate genuine or original equipment quality repair parts to fix your CTS. It's not all the time that you realize that you have to buy a replacement Catalytic Converter to repair your car or truck.

What Catalytic Converter does for your vehicle.

Achieving maximum fuel efficiency while reducing emissions on your car or truck depends on your use of properly functioning exhaust and emissions parts. Your Cadillac CTS catalytic converter has been installed thanks to a federal mandate that is decades old. Inside every catalytic converter are cells made from platinum and/or rhodium arranged in a honeycomb pattern that change the harmful emissions of your Cadillac CTS from carbon monoxide and hydrocarbons to carbon dioxide and water. Thanks to this chemical reaction, automakers could now curb their contribution to air pollution, which is why every vehicle made today has a catalytic converter.
