Description
Overview
The Flowmaster 223 Series Universal Catalytic Converter is a premium-grade, 3-Way emissions solution built with a 3.00 in. inlet and 3.00 in. outlet for high-flow exhaust systems. Manufactured in the USA with a stainless steel outer shell and a ceramic core substrate, this converter is engineered to meet federal EPA emissions requirements across a wide variety of applications, making it a dependable choice for catalytic converter replacement on trucks and performance vehicles with a maximum engine size of 5.9L and a max gross vehicle weight of 5500 lbs.
What Does a Catalytic Converter Do?
If you’ve ever wondered what a catalytic converter is or what catalytic converters do, the answer is emissions control. A catalytic converter uses precious metal loading over a ceramic core to convert harmful exhaust gases into less harmful output. Flowmaster carefully engineers the internal substrate and precious metal loading in this 223 Series unit for maximum efficiency, helping keep your vehicle running clean while maintaining the strong flow characteristics enthusiasts expect.
Key Benefits
One of the most common headaches with lower-quality converters is a triggered Malfunction Indicator Lamp (MIL). This Flowmaster converter is specifically engineered to keep the MIL light off, so your catalytic converter fix or repair doesn’t turn into a recurring dashboard warning. Whether you’re tackling a full catalytic converter replacement or upgrading an aging system, the round core design and excellent flow make it a smart, durable investment.
