Depending on when your vehicle was manufactured, your vehicle will be equipped with either an OBDII or Pre-OBDII diagnostic system. OBDII systems were not mandatory until 1996 so most vehicles manufactured prior to 1996 are Pre-OBDII with some exceptions. All cars and light trucks built and sold in the United States after January 1, 1996 were/are required to be OBDII equipped. Please refer to your vehicle documentation and/or manufacturer to determine your vehicle's OBD status.

The catalytic converter is a marvel of chemical and engineering technology. It cleans gases passing through vehicle's exhaust systems. Catalytic converters typically consist of a ceramic or metal honeycombed monolith substrate that carries precious metal catalysts. The coated substrate is wrapped in an protective thermal mat that expands when heated, securing and insulating the substrate, which is contained in a tough stainless steel shell and becomes a component in an engine exhaust system. As exhaust gases pass over the catalysts, chemical reactions occur that convert pollutants into harmless gases and water. Hydrocarbons combine with oxygen to become carbon dioxide. Nitrous oxides react with carbon monoxide to produce nitrogen and carbon dioxide, and with hydrogen to produce nitrogen and water vapor. AP Exhaust chemists and metallurgical engineers have this expertise.
