The catalytic converter is an important part of a car's emissions control system. It helps to convert harmful pollutants such as carbon monoxide and hydrocarbons into less harmful gases. Without a catalytic converter, these harmful pollutants would be released into the atmosphere.
If your car has oxygen sensors, they can help the engine run more efficiently and may provide some emissions control, but they are not a replacement for a catalytic converter.
If you're considering removing the catalytic converter from your car, be aware of the potential risks and legal implications.
