Will Removing the Catalytic Converter Increase a Car's Power?

[VonAnthony]

Removing the catalytic converter can indeed increase a car's power. The catalytic converter is the most important external purification device installed in a vehicle's exhaust system. It converts harmful gases such as carbon monoxide, hydrocarbons, and nitrogen oxides emitted from the car's exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction reactions. Its conversion function imposes some resistance on exhaust emissions, and its removal can enhance the vehicle's performance to a certain extent. However, after removing the catalytic converter, the vehicle's exhaust emissions will exceed the standard, causing severe pollution to the atmosphere. The oxygen sensor and OBD emission diagnostic system will detect the excessive emissions, triggering the engine warning light immediately, which cannot be reset.
