Exhaust Systems: Purpose, Location, Principle of Work

Everyone knows that the general purpose of the exhaust system is to get the polluted gases out and away from your vehicle. But even though this sounds very simple, the process itself is much more complicated than that. So if you’re wondering what exactly does an exhaust system, and how does it do it, keep reading!

The purpose of the exhaust emission system is to take care of the toxic emissions that your car produces. It will direct all the harmful gases away from the driver and the passengers and it will reduce the emissions your car releases into the environment, helping keep the air clean. An additional benefit of the exhaust system is that it significantly reduces the noise that your car makes. An exhaust that’s kept in good working order will help you reduce noxious gases and keep your car’s sound pleasant while it runs.

The part of the exhaust system that you can see is the tailpipe under the back of your vehicle. However, the entire exhaust system is much larger and much more involved than just that – it runs from the engine, along the underside of your vehicle up to your tailpipe.


The way the exhaust works is, as your car starts emitting fumes, the manifolds (which are part of the system connected to the engine) harness the gases into the system. Then your car’s catalytic converter (also known as the cat) takes charge. It takes the gases in the system, analyzes them and transforms them into less harmful or not harmful at all. Because all of these processes are quite noisy, the muffler helps keep them quiet. What’s left of the emission exits your vehicle through the tailpipe.

The first thing people notice when their exhaust system malfunctions, is the amount of noise that their vehicle makes. The sounds your car makes when the exhaust system is not in a good working order are unpleasant. Another sign is the extensive use of gas, making your engine very inefficient. As soon as you notice one of these problems, make sure to stop by a repair shop. If you delay fixing these problems, they can end up damaging your car even more, which in turn will result in more expensive repairs.
