Nowadays, most car owners prefer using a robust and highly durable catalytic converter while frequently using their cars. The catalytic converter is a part of your car engine’s exhaust system that not only reduces the air pollution it causes but also ensures all other harmful substances are adequately absorbed.
But the question here is, can you drive without a catalytic converter?
A direct answer to this question might be “Yes”, but there is more to it than just a simple yes! If you drive a car without a catalytic converter, it might not bring too much harm to you in person, but if you want your environment to be safer, you must use it while driving.
And if you are driving without catalytic converter, you might also face legal issues as in some states; it is illegal to not have a catalytic converter in the car, more so because your vehicle will fail the emission testing also!
So, if you have been thinking, can you drive a car without a catalytic converter? You should know that its absence does not damage your vehicle or the engine anyway. But for your legal safety and the safekeeping of the environment, you must use a catalytic converter in the car.
In this article, we will discuss what is the function of a catalytic converter, what happens if you drive without a catalytic converter, whether it’s illegal to drive without it, and other relevant details about the same. So, keep reading to know everything in details.
What is a Catalytic Converter and What Does It Do for the Car?
Before we proceed to know whether driving without a catalytic converter is ok or not, we must first understand what is a catalytic converter and how it works in your car’s system. Well, as is evident by its name, a catalytic converter is a catalyst between your car engine and the harmful chemicals it draws within.
You might be eager to learn about what is the main purpose of a catalytic converter. To be precise, it is a part of the car’s engine system which converts harmful exhaust gasses like carbon monoxide, nitrogen dioxide, nitric oxide, and other hydrocarbons into water vapors or carbon dioxide that are less harmful in comparison.
It is not a new technology, and it is present in mostly all cars in today’s time. But most people do not think so deeply about it because not having it doesn’t damage your car’s system. But then you might think, what is so special about a catalytic converter that we have picked such a topic to elaborate on.
Firstly, it spreads less pollution when you have it in your car, and secondly, you can be saved from legal problems. We will read more details about it as the article keeps unfolding. Hopefully, in this section, you have got a clear idea of what is a catalytic converter and why do you need one!

Can You Drive a Car Without a Catalytic Converter?
For all the car owners who have been looking for an answer to can a car run without a catalytic converter, they must know that a car can start and run as well if it doesn’t have a catalytic converter.
Before the 1970s, when the trend of catalytic converters was not so in among the car manufacturers, cars ran perfectly fine without them. It is only after that era that the car manufacturers have resorted to providing a catalytic converter to clean the car engine of harmful gasses and protect the environment as well.
The next question that you might have on your mind is; can you drive your car without a catalytic converter? Again, it’s a yes! You can drive without having a catalytic converter in your car as it doesn’t cause damage to your car’s engine system.
But the question is, should you do it anyway? Then the answer is a big NO!
The catalytic converters might not cause immediate harm to your vehicle’s engine system, but with a long-term effect, it might damage the engine as the harmful exhaust gasses won’t get filtered inside in the absence of the catalytic converter. Thus, driving without a catalytic converter is not at all recommended!
The next big thing that most car owners want to know is whether it is safe to drive without a catalytic converter. If you ask from the legal point of view, it is not safe to drive without a catalytic converter in the US since you can be held for violating the state laws
But suppose it is about having issues in your car or being prone to damages. In that case, you can be sure of the safety as the absence of a catalytic converter does not bring any harm to the vehicle immediately.

What Happens If You Remove the Catalytic Converter?
Though it has already been discussed that removing a catalytic converter won’t do much harm to the vehicle, but it can affect the environment and bring you under legal complications as well.
So, you still need to know the specific pros and cons of removing catalytic converter that we are going to discuss in this section. Go through them entirely and be clear about the differences inevitably. Here we go:
Pros of Removing a Catalytic Converter:
The Car Exhaust Sounds Better
One of the appreciable advantages of removing catalytic converter from your car is that the car exhaust sounds better without it.
When the catalytic converter runs inside the car engine, it makes a noise that combines with the sound of the car engine as well, and thus, it becomes a bit unwanted at times.
So, if you wondered, will removing the catalytic converter make exhaust louder? You must know that it will only make the exhaust sound smoother and less noisy simultaneously!
The Car Engine Can Be Operated at a Lower Temperature
This is one of the advantages of removing catalytic converter that car owners prefer experiencing. When the constriction that the catalytic converter produces during the process of exhaustion is prevented by removing it, the heat under the hood is automatically lowered or controlled.
It means that your car engine will need lower temperatures to operate, which will also reduce the regular wear and tear of the car as it will experience less friction as well.
So, driving without a catalytic converter will reduce the heat under the hood and protect your vehicle against damage at the same time.
The Car Archives Better Gas Mileage
Are you still thinking about what happens if you remove the catalytic converter? Well, your vehicle achieves better gas mileage when you do so!
We all know how straining the catalytic converter is upon the engine because of its constructive design. And when you remove it, it will lower the constrictions as the engine would not have to produce the same energy to operate.
This, in turn, would improve the fuel consumption, and you can expect better gas mileage of the vehicle as well. Therefore, running the car without catalytic converter means you save more bucks on gas fuel.
You Get Access To More Fuel Options
Most fuel stations in the US used to sell leaded and unleaded gasoline back in the 90s. It was because the catalytic converters would not allow leaded fuel to run through them as they could trigger several damages to the vehicle parts.
But what happens if you don’t have a catalytic converter?
It will allow several high specific leaded fuel and other similar fuel options to be used in the vehicle that will shell out maximum productivity and provide protection to the vehicle parts at the same time. Thus, removing the catalytic converter from the car would give you acces to more fuel options!
Cons of Removing a Catalytic Converter:
Legal Complications Will Arise If Found Out
One of the primary disadvantages of removing catalytic converter from your car is that you may face legal complications if you are caught. Yes, across the US, it is prohibited to own a vehicle that doesn’t have a catalytic converter or in which the converter is removed.
It’s mainly because the car cannot pass the emission test in the absence of the catalytic converter. And the penalty for driving without a catalytic converter can be harsher. So, it is recommended not to remove the catalytic converter in the car if you want to avoid legal complications.
More Polluted Emissions Causing Environmental Harm
Do you realize what happens if you drive without a catalytic converter in your car? Beyond just the legal complications, it can cause more damage to the environment in which you are driving the car.
The key purpose of the catalytic converter is to convert harmful exhaust gasses to less harmful substances. These gasses get outside the car engine and cause pollution in the air if the catalytic converter is not present in the vehicle.
Thus, the environment around you is extremely polluted in the absence of a converter.
The Car Engine Creates More Noise
If you ask does removing catalytic converter cause problems, you must know that it actually does! And one such problem is that the car engine makes more noise when the catalytic converter is not present.
However, you have already read that the car exhaust makes better noise in the absence of the converter, but it is the opposite when it comes to the entire car engine.
If the car windows are not up and the car engine is full, then the noise it shall produce might not be quite pleasant. Without the presence of a catalytic converter, the car engine makes more noise, and that is one disadvantage you must watch out for!
A Fault Code May Be Triggered Against Your Vehicle
There are several advantages and disadvantages of removing catalytic converter, but among all, this disadvantage sounds to be more defaming. When you do not have a catalytic converter in your car, it may trigger fault codes in your vehicle out of nowhere.
Your car’s check engine light might get displayed in the absence of a catalytic converter in the vehicle. Though it can be controlled in some vehicles, doing it would not show other faults for that matter. So, if you do not want to be triggered with a fault code, always stick to a catalytic converter!
Consumption Of More Fuel While Driving
If you wonder; will removing catalytic converter harm engine, you must know that it doesn’t! But it definitely harms your pockets (pun intended) because your car consumes more fuel when the catalytic converter is not present in the car exhaust system.
The catalytic converters are not only used for eliminating harmful gasses from the car engine but also to balance the car’s fuel economy.
Thus, if you remove it, the fuel consumption may increase, which shall burn your pocket too. It is so because the oxygen sensors are burning more gas than usual, which burns more fuel in return!
Do you know? How Long Can You Leave a Car Without Starting It?
How Long Can You Drive a Car Without a Catalytic Converter?
Now that you know what a catalytic converter is and what are the pros and cons of not having it, you must be eager to learn; how long can you drive without a catalytic converter, isn’t it? In simple words, you can drive without a catalytic converter as long as you wish to keep traveling. But there is a catch!
Driving too long without using a catalytic converter on your car’s engine can bring more damage that might not be too relevant during the initial days.
Having said that, driving without a catalytic converter might not be unsafe, or it is not that it harms your car engine too severely. Still, with passing time, the harmful exhaust gasses might just bring unwanted harm to the car engine that you cannot think of initially.
Also, with time, as the harmful gasses do not get catalyzed into less harmful gasses, they will be more dangerous to the environment around and will create more air pollution than usual. Thus, driving long distance without a catalytic converter is not at all recommended!

Is It Illegal to Drive Without a Catalytic Converter?
Yes, if you reside in the US, it is illegal to drive without having a catalytic converter in your car. So, if you ask, is it illegal to not have a catalytic converter in your vehicle, consider the answer to be a yes.
It might not be banned in other parts of the world, though! But in the US, you violate federal and state laws if you remove or drive without a catalytic converter in your car.
Suppose you do not have a catalytic converter in your car. In that case, it will not pass the preliminary emission test, and that is enough to answer why it is illegal to drive without a catalytic converter!
Also, the catalytic converter works toward breaking the harmful hydrocarbons and other gasses into substances that cause less pollution.
So, if you ask us, is it ok to drive a car without a catalytic converter, we would suggest a clear no because it harms the environment drastically! However, you may still remove it if the age of the car is exempted from the ruling!
