Description
Overview
The Flowmaster Catalytic Converter-Universal-200 Series is a compact, high-flow emissions component engineered for custom exhaust builds where space is tight and heat is high. Built with a spun stainless steel outer casing measuring just 4.00 inches in diameter and 8.00 inches long, this universal-fit converter slips into demanding installs where full-size units simply won’t clear. If you’ve been researching what a catalytic converter does, the answer is straightforward: it uses a coated substrate to convert harmful exhaust gases into less harmful compounds as they pass through the exhaust stream. This 3-Way design targets that conversion in a rugged, weld-on-ready package.
Built for Severe-Duty Performance
At the heart of this catalytic converter is a High Flow 200 Cell Metallic Substrate. Unlike ceramic cores, the metallic substrate material is designed to withstand severe-duty, high-temperature applications, making it a smart choice for hard-working builds. The round core shape and standard-grade construction keep exhaust flowing freely while maintaining the emissions function that gives it its purpose. With 2.50-inch inlet and 2.50-inch outlet connections, it integrates cleanly into a wide variety of universal exhaust layouts.
Intended Applications
This converter is intended for customized Pre-OBDII racing applications and as a “green” solution for vintage hot rods or vehicles that did not originally come equipped with catalytic converters from the factory. It meets all EPA 49-state requirements, making it a practical answer when weighing catalytic converter replacement cost against the cost to change catalytic converter setups on older and custom rigs. Whether you’re planning a catalytic converter replacement or a fresh custom exhaust build, this unit delivers Flowmaster quality in a compact footprint. It is rated for a maximum engine size of 5.7L and a gross vehicle weight up to 6000 lbs.
