Description
Overview
The Flowmaster Catalytic Converter-Universal-225 Series is a Premium Grade, 3-Way universal converter built to meet federal EPA emissions requirements across a wide variety of applications. With a 2.25 in. inlet and 2.25 in. outlet, an oval core, and durable stainless steel construction, it’s engineered as a reliable catalytic converter replacement for 49-state vehicles. Manufactured in the USA, this Flowmaster Federal converter pairs excellent flow characteristics with a carefully engineered ceramic substrate and precious metal loading to keep your exhaust system performing the way it should.
What Does a Catalytic Converter Do?
If you’re asking what a catalytic converter is or what catalytic converters do, the answer is simple: a catalytic converter treats the exhaust gases leaving your engine, converting harmful emissions into less harmful compounds before they exit the tailpipe. This 3-Way converter is designed to handle that job efficiently while helping keep the “MIL” (Malfunction Indicator Lamp) light off — a common frustration with lower quality converters. Whether you’re tackling a catalytic converter repair, a catalytic converter fix, or a full catalytic converter replacement, this unit is built to restore proper emissions function.
Key Benefits
Flowmaster’s internal substrate material and precious metal loading are carefully engineered for maximum efficiency and to avoid MIL code issues. The stainless steel outer shell delivers maximum durability, and an included heat shield adds protection where it’s needed. As a universal converter, it offers flexibility for many builds — making it a smart, cost-conscious answer when you’re weighing catalytic converter price against long-term reliability.

Fitment & Installation
This is a Federal (49-state) universal converter — it is not CARB compliant and is not legal for sale or use on vehicles licensed or operated in the state of California (Emission Code 2, CARB Executive Order Number: Not Applicable). It is rated for applications with a maximum engine size of 5.9L and a maximum gross vehicle weight of 6,515 lbs. Because it’s a universal design with weld-on, slip-fit inlet and outlet connections, installation requires welding and/or fabrication and should be performed by a qualified technician. Refer to the Flowmaster application guide for specific part number and vehicle applications. Please note the California Proposition 65 warning applies to this product. The converter is Not Air Tube Kit Adaptable.
