When it comes to upgrading your vehicle's exhaust system, one of the most popular modifications is installing high flow cats. But before making the leap, many car enthusiasts question if these aftermarket additions will trigger a check engine light. This is where the debate on whether high flow cats will throw a code comes into play. With the advancement of engine management systems and sensors, it's essential to understand the potential impact of high flow cats on vehicle performance and emissions. In this article, we'll delve into this hotly debated topic and explore the technicalities of how high flow cats are engineered to balance performance gains and emissions compliance. Get ready to dive deep into the world of automotive upgrades and exhaust systems.
High Flow Cats Vs. Engine Control Module: Will They Throw a Code?
Learn how high flow cats and the Engine Control Module (ECM) interact with each other and whether or not installing high flow cats will cause your ECM to throw a code.
The Role of Oxygen Sensors in High Flow Cats
Gain insight into the function and importance of oxygen sensors in high flow cats and how they impact the ECM's ability to detect and respond to the amount of oxygen in the exhaust stream.
Understanding the Difference Between OBD-I and OBD-II Systems
Delve into the mechanics of On-Board Diagnostics (OBD) systems and how the difference between OBD-I and OBD-II can affect whether or not high flow cats will throw a code.
Increasing Horsepower Without Throwing Codes: How to do it with High Flow Cats
Get tips and tricks for installing high flow cats and maximizing horsepower while avoiding the dreaded code throw from your ECM.
Breaking it Down: Why High Flow Cats Don't Always Throw Codes
Discover the variables that can affect whether or not high flow cats will set off a code from your ECM, from the type of vehicle to the brand and quality of the high flow cat.
Differentiating Between Permanent and Transient Codes for High Flow Cats

What are high flow cats?
High flow cats are catalytic converters that allow better flow of exhaust gases compared to the stock catalytic converters. They both reduce pollutant emissions and increase power output.
Will high flow cats throw a code?
High flow cats may throw a code if they do not meet the original equipment manufacturer's (OEM) specifications. However, there are many high flow cats available that are designed to pass emissions and not throw a code.
What is the main cause of a code being thrown with high flow cats?
The main cause of a code being thrown with high flow cats is if the original equipment manufacturer's specifications are not matched. The OEM ensures that a specific amount of back pressure exists in the exhaust system.
What will happen if high flow cats throw a code?
If a high flow cat throws a code, the check engine light will illuminate, and vehicle performance may decrease. Additionally, the vehicle may fail an emissions test or violate local environmental regulations.
What are the benefits of using high flow cats?
The primary benefits of using high flow cats include increased power output, improved fuel economy, and reduced emissions. Also, high flow cats have a louder exhaust tone due to more straightforward airflow through the exhaust system.
Will High Flow Cats Throw a Code: A Recap
In summary, high flow catalytic converters (cats) can potentially cause a "Check Engine" or "Service Engine Soon" light to appear on a vehicle's dashboard. This is due to the fact that high flow cats allow for more exhaust gases to pass through, which can trigger oxygen sensors and cause them to send false readings to the car's computer system.
Additionally, using high flow cats may not comply with emissions regulations in certain states or countries. It is important to research and confirm whether the use of high flow cats is legal before installing them on a vehicle.
To prevent the potential issue of codes being thrown, vehicle owners can invest in high quality and reputable high flow cats, as well as properly tune their car's engine to work with the new catalytic converters.
By considering the potential consequences and taking the necessary precautions, car enthusiasts can still enjoy the performance benefits of high flow cats while minimizing the risk of code issues and maintaining their vehicle's compliance with emissions regulations.
