A catalytic Converter is one of the essential parts of the car that keeps the car running. Therefore, you should have proper knowledge about the pros and cons of a high-flow catalytic converter to avoid any issues in the first place.
High Flow Cats reduce the consumption of fuel, improving the fuel economy, and they also add more power to the car.
These are some pros of the high flow of the catalytic converter. However, they also have several cons, such as loud noises and odor in the car, and they can turn check engine lights on.
So, you should have some basic knowledge about it to avoid all the cons and keep your car in the best condition. To let you know more about it, here are some of the pros and cons of the cats discussed briefly.

What Is A Catalytic Converter?
Before knowing about the pros and cons of the cats, let’s talk about what a catalytic converter is and what it does. The catalytic converter is one of the important components of the car that fits into the car’s exhaust system, and its job is to reduce the emission of harmful gases and other components from the engine.
- The role of the Catalytic Converter can also be found in heavy-duty trucks, buses, construction vehicles, airplanes, and other applications. The engine exhaust gases are fed into a chamber through a passage called the catalytic converter.
- This chamber is the heart of the catalytic converter. Its primary function is to reduce harmful hydrocarbon emissions from the vehicle’s engine by converting them into water and carbon dioxide.
- Exhaust gases contain many harmful pollutants, including nitrogen, carbon monoxide (CO), and hydrocarbons.
These pollutants are toxic to humans and animals and are responsible for health problems such as bronchitis, heart disease, anemia, and cancer. So the primary role of a catalytic converter is to reduce these hydrocarbon emissions from a vehicle’s engine.
The catalytic convertor works by passing exhaust gas through a fine-mesh honeycomb or ceramic that contains a unique catalyst. This catalyst comprises platinum, rhodium, and palladium deposited on the ceramic substrate in the form of tiny particles called catalyst support.
Do High-Flow Cats Make A Difference?
Yes, high flow makes a difference as it positively affects the exhaust and allows gases to move freely. So this helps to improve the fuel economy and help boost the power of the car. So if you want power and better fuel economy, you can surely go for this upgrade in your vehicle.
In the past, high-flow cats were very expensive, so now better and cheaper options are available.
So you will be happy to know that these can be done for a few hundred dollars. The best part is that no one can notice, and there is no sound difference, even though most people think they are more powerful as it’s just a small thing.
This is very easy to install as it only requires you to cut a line in the hoses and attach them back.
However, make sure that you make sure that the hoses are not damaged as there will be a lot of pressure. If buying the parts yourself, you need to ensure that they are the same as what is on your car; otherwise, it will not fit.
Do High-Flow Cats Restrict Power?
If you want to have high flow cats upgrade, then you should know that a stock exhaust might cause an issue when it comes to receiving the fullness of the power of a high flow catalytic converter.
Of course, everybody wants an upgrade that adds more horsepower to the car. Still, they do not seek the info about it before upgrading about how it’s going to affect the vehicle and whether it is suitable for their car or not.
So it is better to have experts’ advice before going for any upgrade. In addition, the catalytic converter needs to be coordinated with other modifications in your car to perform in optimal condition.
So, a high-flow catalytic converter upgrade is advised for people with turbo or supercharged cars. Thus it would be best if you did not go for an upgrade yourself; always ask the mechanic and car expert about it to ensure it is safe for your car.
But the thing is when you do a high flow catalytic converter, the most common and natural product to be replaced with it is the cat exhaust system.
Thus you should keep in mind that getting high-flow cats does restrict more power from getting through your engine if it has a stock exhaust system.
How Long Do High-Flow Catalytic Converters Last?
It is one of the common queries of people before going for the upgrade, so you should know that high-flow catalytic converters are designed to last for about 100,000 miles. They are said to last long as your vehicle’s life, making them a plus point.
Suppose you buy a high-flow catalytic converter; you can expect it to give you an extended lifespan and help your car run efficiently. The performance of the vehicle is enhanced.
They are designed in such a way that they can withstand a rigorous environment, which makes them the perfect choice for buyers. They are also said to be safe for your engine.
The catalytic converter is one of the most important components in a vehicle. On top of that, it plays an important role in reducing the emission level of a car and increasing fuel efficiency.
Do High-Flow Cats Smell?
Yes, one of the cons or demerits of using a high-flow cat is that have an exhaust odor smell that you can notice while driving the car at a low speed or gears.
The cause of this odor is the overheating of the catalytic converter, which leads to the heating of fuel inside and results in smell.
Do High-Flow Cats Require A Tune?
No. High-flow catalytic converters do not require tuning as they are well designed to work at high speed and emission levels.
They also do not require regular maintenance, which removes the lot from your work plate. Thus, the high-flow cat is a good investment if you want to increase the car’s fuel economy, performance, and power.
