he catalytic converter is a crucial component of the exhaust system in Fits Subaru vehicles, including the 1999-2005 Forester, 2000-2005 Outback, Legacy 2002-2005, and Impreza. Its primary function is to reduce the amount of harmful pollutants that are emitted from the vehicle’s exhaust.
The Fits Subaru catalytic converter is made up of a ceramic or metallic substrate that is coated with precious metals such as platinum, palladium, and rhodium. The exhaust gases pass through the substrate, and as they do, the precious metals trigger a chemical reaction that converts the harmful pollutants, such as carbon monoxide, hydrocarbons, and nitrogen oxides, into less harmful substances, such as carbon dioxide, water vapor, and nitrogen.
