Performance Catalytic Converters

High-Flow, Direct Fit & Universal Converters

The catalytic converter on your vehicle is part of your emissions control system. The catalytic converter converts harmful gases such as Carbon Monoxide (CO) and unburned Hydrocarbons (HC) into less harmful water vapor and Carbon Dioxide (CO2). Your original converter was built to last and carries an 8-year, 80,000- mile, federal emissions warranty from the manufacturer (1996 or later vehicles), but when it fails, look to CARiD for a quality replacement.

Catalytic converters are manufactured in several configurations. There are 2-way converters, 3-way converters and 3-way converters with an air tube. Direct fit converters are made for specific applications and made to bolt on to the vehicle, while universal converters will require cutting and welding to connect into the exhaust system. The converter must also be made to conform to the emissions regulations where it will be used, which is why there are converters for 49-state vehicles and converters for California vehicles.

All catalytic converters consist of a ceramic and/or metal honeycomb substrate encased in a cylindrical stainless steel enclosure. The actual catalysts from which the component gets its name are precious metals like rhodium, platinum and palladium, which are applied to the surface of the substrate. A catalyst is a substance that causes a chemical reaction without itself being a part of the reaction. The substrate is so shaped so the exhaust gas, as it passes through the converter, can be exposed to as much catalyst as possible.

A 2-way catalyst, also known as an oxidation catalyst, converts CO to CO2, and HC to CO2 and water. These converters were used on older vehicles. A 3-way converter does the same thing but also reduces oxides of nitrogen NOx to nitrogen and oxygen, which is why this type of converter is called an oxidation/reduction catalyst. All modern catalytic converters are 3-way converters. 3-way converters with an air tube are connected to the engine’s air injection system, which supplies additional oxygen on some vehicles to facilitate the chemical reaction.

Your catalytic converter can be replaced with an aftermarket unit if it’s beyond the emissions warranty and it’s plugged, contaminated, rusted out, or physically damaged, or if the vehicle fails an emissions inspection. However, you should be aware that if an engine malfunction caused the old converter to fail, the engine must be properly diagnosed and repaired or the replacement converter may fail again for the same reason. A properly functioning catalytic converter is critical to good engine performance and clean air.

2006 Subaru Legacy | Posted by Daniel | (Woodbridge, VA)

Product looks good, materials used are good quality, need improvement in welding, installation easy to medium one nut on each side of flanges hard to tighten. Original converter much easy to install.
