The function and purpose of Catalytic Converter.

Getting the most out of your car or truck depends on how well you maintain your engine and exhaust parts. Your GMC Sierra 2500 HD catalytic converter is likely the single most effective pollution control device on production vehicles today. There are a host of precious metals, mostly platinum, in the catalytic converter that change the harmful emissions of your GMC Sierra 2500 HD from carbon monoxide and hydrocarbons to carbon dioxide and water. Thanks to this chemical reaction, automakers could now curb their contribution to air pollution, which is why every vehicle made today has a catalytic converter.
