What are the impacts of not having a catalytic converter?

[OJourney]

The following are the impacts on a vehicle without a catalytic converter: 1. The engine emission warning light on the combination instrument panel will illuminate, and the vehicle's exhaust emissions will severely exceed standards. 2. While driving on the road, the vehicle may be caught for violations and face penalties such as fines. 3. If the vehicle reaches the annual inspection period, it will fail the inspection. Additional Information: The catalytic converter is installed between the engine exhaust manifold and the muffler. It converts harmful gases such as CO, CH, and NOx produced by engine combustion into harmless carbon dioxide, water, and nitrogen through oxidation and reduction reactions within the catalytic converter's honeycomb-structured ceramics and precious metals. Since this converter can simultaneously transform three major harmful substances in the exhaust into harmless ones, it is called a three-way catalytic converter.
