Catalytic converters are used to reduce harmful and environmentally damaging emissions from the car’s exhaust system. Carbon monoxide is the primary pollutant. It is reduced to a minimum level by the catalytic converter, with little or no effect on the environment. ​

Many states in the US conduct a yearly emissions inspection on vehicles to ensure their catalytic converter are working properly. This is where gutting your catalytic converter becomes bad and the disadvantages of removing the catalytic converter also make a huge difference. Though there are still some benefits of removing catalytic converter to some person is it really worth it? I will also compare the horsepower gain from removing the catalytic converter so you know and make your decision.

• With those in mind, let’s get started by looking at the pros & cons of removing a catalytic converter.

Advantages and disadvantages of removing catalytic converter (pros and cons of removing catalytic converter)

Cons and benefits of removing catalytic converter 

1.     Increase horsepower.

People choose to get rid of a catalytic converter for added horsepower. In order to process all the ignition residuals, and to make sure that no harmful pollutants are released into the environment, catalytic converters create back pressure which reduces engine power. The engine can burn hydrocarbons to increase its power output significantly, as it is less dependent on oxygen. This is especially true for older vehicles, where the catalytic converters were not designed to take into account various performance measurements.

2.     You will Get Less Heat from the Engine.

The engine will also be less laden due to the removal of the catalytic converter. This results in lower operating temperatures which then reduces the engine’s workload and heat. The engine is much more efficient and lighter when it’s hot. Let’s now look at the pros and cons of removing the catalytic converter.

The disadvantages of removing catalytic converter

These are the cons of removing Catalytic Converter:

1.     Frequent stalling and braking of the car

You will see a variety of clues that indicate a damaged or missing catalytic converter. Without a converter, the vehicle’s fuel economy will drop quicker and you will experience a decrease in power. If the converter is plugged, it can cause excessive pressure and cause stalling.

2.     Not Environment Friendly

It is our moral responsibility as humans and inhabitants of the planet Earth to protect and care for the land we call home.The environment is not worth a little boost, or even a small amount of extra gas mileage. It’s also not worth the additional noise from the exhaust. It is now considered unethical to remove the catalytic converter from a car, especially in these times of environmental concern. Uncontrolled pollution by an engine is the greatest drawback when removing a catalyst converter.

3.     Damage other parts.

The removal of the converter can also cause damage to other parts of your car like the oxygen sensor, which works in tandem with the catalytic converter. The check engine light may turn on which could cause your vehicle to fail an emission test, as I mentioned earlier.

4.     Raspier Exhaust Noise

A loud engine is a must-have for anyone. It is a loud engine that I cannot say if it is the most pleasant, but it has a raw feeling like no other. This sound is loved by both casual drivers and serious motorheads alike. Some petrolheads even love to modify the exhaust to make it heavier and more powerful. If one loves the loud, uninhibited engine sound, the muffled mumble might be a bit annoying.

5.     Failure to Pass the Emissions Test

To renew the PUC certificate in India, you must pass an emissions test once every six months. To renew your pollution license, you must meet certain emission standards. Catalytic converter is one main emission control device in your car that helps keep emissions under control. You will likely get higher than usual results if you forgo or remove the catalytic converter during your next emissions test. Failing the test could also mean that you drive without a PUC certificate, which can be illegal in certain states.

6.     Noise and muffled exhaust

Exhaust noises, as we have already mentioned, can sometimes be too significant for some people. In these cases, a catalytic converter can prove to be a nuisance. This is true noise pollution. so now let’s look at the horsepower gain from removing catalytic converter

What is the horsepower gain from removing catalytic converter

You can gain an Extra 15 horsepower from gutting or removing cats.  The horsepower gained by removing the catalytic converter can depend on the car engine size. Larger engines can gain more horsepower if the backpressure is reduced. After removing the CAT, your horsepower can be doubled to reach 30 horsepower.

will removing catalytic converter harm engine

Is it possible to harm the engine by removing the catalytic converter? and does removing catalytic converter cause problems? My answer to this question is no. The removal of your car’s catalytic convert will not cause damage to your vehicle’s engine. In fact, it will increase your car’s performance by having less work. If your state requires them, however, removing the catalytic converter will make your car not comply with emissions tests.  Only High mileage cars may be able to benefit from having their converters removed. 

Easy step on Removing or Gutting Your Catalytic Converter

It is easiest and most cost-effective to gut of catalytic converter by removing it from your car. You can lift the car or place it on stands, or any other means to reach underneath the converter. You should remove your catalytic converter after it has been removed from the vehicle for several hours. Exhaust piping can be very hot so make sure you do this right away.

The heat can cause the metal to expand making it harder to remove. The inside of the converter will look like honeycombs once it’s removed.
