Description
Overview
The Flowmaster 223 Series Universal Catalytic Converter is a premium-grade, 3-Way emissions solution engineered to meet federal EPA requirements across a wide variety of applications. Built in the USA with a stainless steel outer shell and a carefully engineered ceramic substrate, this converter is designed to deliver excellent flow while keeping your vehicle’s emissions system running clean. With a 2.50 in. inlet and 2.50 in. outlet, it slots into countless custom and replacement exhaust builds where a reliable, durable converter is required.
If you’ve been asking what is a catalytic converter and what does a catalytic converter do, the answer is simple: it’s the emissions component that converts harmful exhaust gases into less harmful output before they leave the tailpipe. Flowmaster’s 3-Way design and precious-metal loading are tuned for maximum efficiency, making this a smart choice for a catalytic converter replacement, catalytic converter repair, or catalytic converter fix on eligible vehicles.
Key Benefits
Lower-quality catalytic converters are a common cause of a lingering Malfunction Indicator Lamp. This Flowmaster unit is specifically engineered to keep the “MIL” light off, thanks to its carefully calibrated internal substrate and precious metal content. The stainless steel construction is built for maximum durability, standing up to heat and the demands of daily driving on applications up to a 5.9L maximum engine size and 6000 lb gross vehicle weight.

Options & Configuration
This is a universal-fit converter, which means it requires welding and/or fabrication to integrate into your existing exhaust. There is no oxygen sensor port and no heat shield included, and it is not air-tube-kit adaptable, so plan your installation accordingly. Because fitment spans many vehicles, always refer to the Flowmaster application guide for the specific part number that matches your setup, and have the unit installed by a qualified technician.
Fitment & Compliance
This is a 49-State (Federal) converter and is NOT CARB compliant. It is not legal for sale or use on vehicles licensed or operated in the state of California (Emission Code 2, No CARB Executive Order). It carries a California Proposition 65 warning. Confirm your application supports a 2.50 in. inlet/outlet, a maximum engine size of 5.9L, and a gross vehicle weight up to 6000 lbs before ordering.
Whether you’re weighing catalytic converter price against a full exhaust rebuild or simply need a dependable catalytic converter replacement, this Flowmaster 223 Series unit combines durable stainless steel construction with proven emissions performance.
