Catalytic Converters:

Catalytic ConverterSince the mid-1970's all cars sold in the USA were required to have a Catalytic Converter installed in the vehicle's Exhaust System.

A catalytic converter first stage reduces or diminishes the nitrogen oxide emissions catalyst by using platinum and rhodium. The second stage is the oxidation catalyst. During this the unburned hydrocarbons and carbon monoxide are reduced by oxidizing or burning. The last stage of the conversion has a control system (oxygen sensor) that monitors the exhaust stream and helps regulate the fuel injection system.

When the oxygen sensor detects the oxygen level problem, it regulates the amount of oxygen in the exhaust through the air-to-fuel ratio. The oxygen sensor will turn on the Check Engine light if the readings fall outside permissible EPA ratings.


Your Exhaust System starts with the Headers. These are attached to your Engine and the header funnels your exhaust to your single or dual pipe exhaust system. The Headers and Header Gaskets normally last the life of your vehicle, but could start to leak. If a gasket is leaking, you may hear a loud noise from the engine compartment and/ or the smell carbon dioxide inside your car. Carbon dioxide can be fatal, so take immediate corrective action and do not drive your vehicle.
