What Catalytic Converter does for your vehicle.

Getting the most out of your car or truck depends on how well you maintain your engine and exhaust parts. Your Hummer H2 catalytic converter has been installed thanks to a federal mandate that is decades old. Inside every catalytic converter are cells made from platinum and/or rhodium arranged in a honeycomb pattern that turn the carbon monoxide and hydrocarbons that your Hummer H2 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.

You've tried the rest, now try the best.
