What Is a Catalytic Converter and What Does It Do?

Your car’s catalytic converter is one of your vehicle’s most essential emissions control devices. It’s a key player in reducing harmful exhaust gases produced by your engine. But what exactly is a high-flow catalytic converter, and how does it work? So, this blog post will explore the ins and outs of this crucial car part so that you can better understand how it works to reduce emissions.

This component is a device that converts harmful emissions from an engine into harmless gases. It does this by using a catalyst, which is a substance that speeds up the chemical reaction without being used up in the process. Meanwhile, they are required by law in many countries to reduce the amount of pollution that vehicles produce.

The primary purpose of this device is to reduce the pollution caused by a car’s engine. In the past, cars emitted much higher levels of pollutants such as carbon monoxide and hydrocarbons. Whenever fuel is consumed in an engine, these pollutants are released. So, catalytic converters were introduced in the 1970s to help reduce these emissions.

Today, all cars sold in Australia must have a catalytic converter, and this has helped to significantly reduce air pollution from automobiles.


Normally, exhaust gas ejected from an internal combustion engine contains poisonous gases and pollutants. So, a catalytic converter converts them into less hazardous chemicals as part of the vehicle’s emission control system.

The main benefit of this component is its ability to reduce the harmful emissions from a car’s engine, making it better for the environment. Another benefit of a high-flow catalytic converter is that it can improve a car’s fuel economy. This is because the converter helps to convert unused energy in the exhaust gas into heat, which can then be used to power the engine. Finally, they can also help extend the life of a car’s engine by reducing the build-up of sediments and corrosion.

Installation Tips

When installing this device, it is important to follow the manufacturer’s instructions. In general, however, a few tips can make the process go more smoothly.

First, ensure the vehicle is in the park or neutral and the parking brake is engaged before beginning work. Next, locate the converter near the exhaust manifold; it will be bolted to the exhaust pipe or flange.

If you are working with a bolt-on converter, loosen the bolts and remove the old converter. And if you are working with a weld-on converter, cut through the old converter with a Sawzall or similar tool. Meanwhile, be careful not to damage the exhaust pipe or flange in the process.

Once the old converter is removed, clean off any debris from the mating surfaces of the exhaust pipe or flange. Then, bolt on or weld on the new converter in its place. Again, follow the manufacturer’s instructions for specific details on how to do this properly.

Finally, start the engine and check for leaks at all joints and connections. If everything looks good, you’re finished!

A catalytic converter is a component that transforms pollutants and toxins in exhaust gas ejected from an internal combustion engine into less harmful substances. By doing this, it plays an important role in reducing emissions from vehicles. So, if you’re interested in learning more about how catalytic converters work and their importance, this article has provided a helpful overview.
