What Catalytic Converter does for your vehicle.

Getting the most out of your car or truck depends on the quality and performance of the parts you use. Your GMC Sierra 2500 HD catalytic converter is the result of about a decade of engineering that took place in the 1960s and 70s. There are a host of precious metals, mostly platinum, in the catalytic converter that turn the carbon monoxide and hydrocarbons that your GMC Sierra 2500 HD produces into harmless molecules of carbon dioxide, oxygen, and some water. This process revolutionized automakers' ability to improve air quality, which is why every vehicle made today has a catalytic converter.
