How High Flow Cats Improve Efficiency

When it comes to improving the performance of your vehicle, there are a variety of modifications you can make. One popular option is installing a high flow catalytic converter, also known as a high flow cat. Not only does this upgrade increase horsepower and torque, but it also has environmental benefits. In this article, we will explore how high flow cats improve efficiency and why they are a great option for your vehicle.

What is a Catalytic Converter?

Before we dive into the benefits of a high flow cat, it’s important to understand what a catalytic converter is and how it works. A catalytic converter is a device that is installed in the exhaust system of a vehicle. Its purpose is to reduce harmful emissions by converting them into less harmful substances before they are released into the atmosphere. This is done through a series of chemical reactions that take place inside the converter.

High Flow vs. Standard Catalytic Converters

A standard catalytic converter is designed to meet emissions standards set by the government. However, these converters can also restrict the flow of exhaust gases, which can decrease the performance of your vehicle. High flow cats, on the other hand, are designed to have less restriction, allowing for a smoother flow of exhaust gases. This results in increased horsepower and torque, as well as improved fuel efficiency.

CARB Legal High Flow Cats

One concern with installing a high flow cat is whether or not it is legal. In California, the California Air Resources Board (CARB) sets strict emissions standards for vehicles. However, there are high flow cats that are CARB legal, meaning they meet these standards and are approved for use in California. These high flow cats have been tested and certified to ensure they do not increase emissions.

Improved Efficiency

The main benefit of a high flow cat is the improved efficiency it provides for your vehicle. By allowing for a smoother flow of exhaust gases, the engine does not have to work as hard to push them out. This results in increased horsepower and torque, which can improve the overall performance of your vehicle. Additionally, a high flow cat can also improve fuel efficiency, as the engine is not working as hard to push out the exhaust gases.

Environmental Benefits

In addition to the performance benefits, high flow cats also have environmental benefits. By reducing the restriction in the exhaust system, the engine does not have to work as hard, resulting in lower emissions. This means your vehicle will be more environmentally friendly and may even pass emissions tests more easily.


High flow cats are a great option for those looking to improve the performance of their vehicle while also being environmentally conscious. By reducing restriction in the exhaust system, they can increase horsepower and torque, improve fuel efficiency, and reduce emissions. Just be sure to choose a CARB legal high flow cat to ensure you are meeting emissions standards. Consider upgrading to a high flow cat for a more efficient and powerful ride.
