The catalytic converter is a key component of your vehicle’s emissions control system, which prevents pollutants from contaminating our environment. It converts the harmful gases Carbon Monoxide (CO), Hydrocarbons (HC), and Oxides of Nitrogen (NOx) created during combustion, and turns them into water, and the less harmful gases Carbon Dioxide (CO2) and Nitrogen (N2). However, as part of the exhaust system, catalytic converters also affect exhaust flow.

Reducing exhaust backpressure and restriction is a proven method of increasing an engine’s power output, and like mufflers, catalytic converters do create some restriction. The converter contains a monolithic honeycomb substrate coated with catalyst materials, usually platinum, palladium, and rhodium. As the exhaust gas passes through the honeycomb structure, it is exposed to the catalyst, which causes the oxidation of CO and HC, and reduction of NOx.

In the quest for maximum performance, you may be tempted to remove your catalytic converter, but this is a bad idea for several reasons. First, it’s against Federal law to remove a catalytic converter and you could be subject to a fine if removal is revealed during a roadside inspection. Second, you’ll fail an emissions test if emissions inspections are required in your area. Finally, converter function is an integral part of your vehicle’s engine control system, especially on 1994 and later OBD II vehicles, and you’ll illuminate the CHECK ENGINE light and may experience drivability problems if the converter is removed.

If you’ve installed a cat-back exhaust and you want to further increase exhaust flow and power, install a high-flow performance catalytic converter. We offer converters with honeycomb substrates specially designed for maximum flow. Unlike ordinary replacement converters, the application of the catalyst to the honeycomb is carefully controlled to prevent coating that could create exhaust flow restrictions. The converter inlet and outlet are constructed with smooth surfaces where they transition into the converter body for unobstructed flow, and the size of the inlet is perfectly matched to the size of the converter body.

A performance converter is also a good choice to replace one that is restricted due to misfire, a rich air/fuel mixture, coolant leaks, or oil burning. Such defects must be repaired or your performance converter will also fail. So whether you’re seeking more performance or replacing a defective unit, we have the performance catalytic converter that will unleash the power and keep your vehicle emissions legal. We offer both direct fit and universal converters. A direct fit converter will bolt right in place of the factory converter, while a universal converter requires pipe cutting and clamping or welding for attachment.
