Catalytic converters are greatly involved with automobile emission control. It is why the answer to the question, “will muffler shop remove catalytic converter?” is not so simple.
Removal of a catalytic converter is essentially illegal in many states. But Yes, it is possible to do so by following the right procedure. Muffler shops will remove catalytic converters by following the guidelines provided by the state. So, planning to do it on your own is not a great idea.
This component is quite controversial amongst car enthusiasts. Some people believe in its necessity, while some refuse to do so. Confused about what should you do? Don’t worry! Because in this write-up, we will be discussing everything related to catalytic converter removal.

Does a Muffler Delete Remove Catalytic Converter?
Catalytic converters are a part of the exhaust system. It catalyzes the harmful gasses released by combustion and muffles the additional sound created by the vehicle. So, it is quite similar to a muffler.
The chances of removing a cat converter during a muffler delete are low. So, no, a muffler delete will not remove a cat converter. A muffler delete process is just what the name suggests. You will only get rid of the muffler and nothing else.
But the cat converter will get removed during a straight pipe exhaust procedure. Lots of people use these two procedures interchangeably, but they are very different.
What Happens to a Car When the Catalytic Converter Is Removed?
Every component in a vehicle has a purpose. A cat converter is not different. It is supposed to react with a toxic gas called carbon monoxide created through fuel combustion. And create carbon dioxide which is later released into the atmosphere.
Since the catalytic converter is related to emission control, removing it without a legitimate reason is illegal. The EPA has strict rules and regulations related to it. In many countries around the world, removing the car’s cat converter is a serious offense.
Federal law in the US makes it illegal to remove a functioning catalytic converter. You can only replace or fix your cat converter if it is damaged, needs to be replaced, or was stolen. If you are caught without a cat converter, you will have to pay serious fines.
These mixed opinions make the cat converter a very controversial component. Some car enthusiasts believe catalytic converters are an important part of a vehicle while some don’t.
When you delete the catalytic converter, your vehicle will no longer be the same. It will face some visible changes. These changes can be both advantages and disadvantages depending on your views.
1. Your vehicle will sound stronger and louder
Catalytic converters are a part of mufflers in regular cars. So, when you do a muffler delete, the cat converter in your car is removed too.
Cat converters work almost similar to a muffler too. The impact of the gases coming from the engine because of the fuel burning and combustion will create a loud noise. This component reduces and muffles that noise.
A lot of people opt for a muffler delete because it enhances the exhaust sound of their car. If you are one of them, then a catalytic converter delete will work as an advantage for you.
But if you are not, you will be able to feel the absence of your cat converter. Because the sound of your vehicle will be significantly louder.
2. You can significantly decrease the engine temperature during operation
A catalytic converter creates a constriction to impact the exhaust gases from leaving the car’s system and entering the atmosphere. Due to the constriction, the engine has to run more efficiently to generate more power.
This creates extra heat inside the engine. When you remove the cat converter, the constriction goes away too. Your engine performs at its full capacity while producing minimum heat.
3. You will get better gas mileage
In some models of vehicles, removing a catalytic converter allows the engine to perform freely, without any constriction.
This improves fuel consumption significantly. This change does not happen to every type of car, so don’t be disappointed if it doesn’t happen to yours.
Even without better gas mileage, your car will still experience a boost in power. It will ultimately lead to efficiency either way.
4. Wide range of fuel options
Catalytic converters can become a roadblock between your car and several types of fuels. For example, if you have a catalytic converter in your vehicle, then you cannot use leaded fuel or leaded gasoline. Because, leaded fuels will destroy the catalyst inside the converter, and will ruin your vehicle too.
When you remove this component from our car, you are receiving access to a wide array of high-performance fuels. High-performance fuels will only boost the performance of your car and keep the engine healthy!
5. Significant rise in horsepower
Most cars can experience a significant boost in power in the absence of a catalytic converter It happens because, with the cat converter’s removal, a strong exhaust gas exit source gets created. It leads to the reduction of engine back pressure.
Also due to the removal of this component, plenty of space frees up. This space allows enough airflow to the combustion chamber of your car. It leads to a faster combustion process, and a stronger car.
So, with a catalytic converter delete, your engine will be able to perform with its maximum power.
Do Muffler Shops Install Catalytic Converters?
