If you remove catalytic converters will check engine light stay on?

In most modern vehicles, removing the catalytic converter will cause the check engine light to illuminate. Catalytic converters are an important part of the vehicle's emissions control system, and their removal can lead to increased emissions of pollutants such as carbon monoxide, hydrocarbons, and nitrogen oxides. These pollutants can cause a variety of health problems, including respiratory irritation, asthma, and cancer.

In addition to causing the check engine light to illuminate, removing the catalytic converter can also lead to other problems, such as:

* Increased fuel consumption

* Reduced engine performance

* Rough idling

* Stalling

* Increased noise

If you are considering removing the catalytic converter from your vehicle, it is important to weigh the potential benefits and risks. While removing the catalytic converter may improve engine performance slightly, it can also cause a variety of problems, including increased emissions, reduced fuel efficiency, and check engine light illumination.

It is also important to note that removing the catalytic converter is illegal in many jurisdictions. Before removing the catalytic converter from your vehicle, it is important to check the laws in your area to make sure that you are not violating any regulations.
