The catalytic converter is part of your vehicle’s exhaust system, but more importantly, it’s also a key component of the emissions system. The catalytic converter takes the Carbon Monoxide (CO), Hydrocarbons (HC), and Oxides of Nitrogen (NOx) created during combustion, and turns them into water, Carbon Dioxide (CO2) and Nitrogen (N2). The device is so named because it contains catalysts, substances that cause a chemical reaction without themselves undergoing chemical change.

    Catalytic converters have been original equipment on most gasoline engine vehicles in the U.S. since 1975. They have evolved since their inception, from 2-way converters to 3-way converters plus air, to the modern 3-way converter. Early 2-way converters, also called oxidation catalytic converters, were so called because they only converted HC and CO. In the late 1970s and early 1980s they were replaced on most vehicles by 3-way converters, which can also control NOx emissions. 3-way converters are known as oxidation-reduction catalytic converters.

    In general a converter is composed of a cylindrical stainless steel enclosure housing a monolithic substrate which contains the catalyst. The most common catalyst materials are the precious metals platinum, palladium, and rhodium. The substrate is constructed to expose as much exhaust gas as possible to the catalyst as it flows through the converter, for maximum conversion and efficiency. 2-way converters use platinum and palladium to oxidize CO and HC. 3-way converters also have rhodium to reduce NOx. Early 3-way converters had a separate substrate that oxidized CO and HC with help from additional oxygen supplied by an air pump. Modern 3-way converters use advanced chemistry, O2 monitoring and computerized fuel control to convert all 3 harmful gases without the need for additional oxygen.

    Various factors can cause converter failure. Internal problems like plugging or reduced conversion efficiency are nearly always caused by engine problems like misfire, rich air/fuel mixture, coolant leaks, and oil burning. Misfires and excessive fuel can cause the converter to overheat and melt the substrate, while oil and antifreeze can coat the surface of the substrate, preventing catalyst exposure to the exhaust. In its location under the vehicle, the converter is also exposed to impact from road debris that could cause structural damage. A clogged converter will restrict exhaust flow resulting in poor performance. Other symptoms of a failed converter include rattling noises, an illuminated Check Engine light, and excessive emissions, which can result in a failed smog test.

    Regardless of the cause for catalytic converter malfunction and symptoms, we can supply you with a replacement that will restore performance and make your vehicle emissions legal. We offer both direct fit and universal converters that are EPA (Environmental Protection Agency) and CARB (California Air Resources Board) compliant. A direct fit converter will fit and function the same as your factory converter, and bolt right in place in your exhaust system, while a universal converter will require pipe cutting and clamping or welding for attachment. We also offer converters for applications where the converter is part of the exhaust manifold. Many of our manifolds with integrated converters come as complete kits with all gaskets, hardware, and shields (as required) included.

    Perfect Fit (Passed Emissions Test)!
    Had a little problem with the shipping confirmation but other than that everything was perfect. Part arrived earlier then expected, looked just like the picture on acrid great condition. Installation was quit and easy bolted right on.
