Meaning and types of exhaust system in a car

Over the years, a lot has been said on what exhaust means and how it works. Just like every other part in a vehicle, the exhaust system plays its role well and ensures the car is working the way it should. Here on Cars9ja are what you need know about automotive exhaust system and the various types we have.

What is the meaning of exhaust system in a car?

The idea behind the design of the exhaust system is to discharge steam or burned gases through the lengthy tube via the rear of the vehicle. So, the exhaust system is a combination of parts or components responsible for the removal of combustion gases from the car engine. To make this process smooth, the catalytic converter comes into play, helping to clean the parts including the gases. The way these gases flow depends on the automotive structural design. While in some cars, the gases flow through one portal, it’s multiple in others.


As earlier iterated in an exhaust system, the catalytic converter reduces air pollution. Other important components include the muffler for noise reduction, exhaust manifold and cylinder head, and the turbocharger for increase in the power from the engine.

Types of exhaust system

Single exit pipe

Single exit pipe is the most popular type of automotive exhaust system since it is affordable and easy to install. This is a situation whereby there is a single exhaust pipe fitted on the vehicle. The fact that it requires single pipe doesn’t make it very effective. The car maker places it mostly on average car due to tis cost effectiveness and ability to work well with the type of workload from the engine. The passengers’ side of the vehicle is usually used as its exit point.


Dual rear exit

This type of exhaust system is usually found on sportscars or even premium cars. It gives the vehicle that sharp look and feel, while playing its supposed role very well. A vehicle with dual rear exit exhaust system will sound quite deep especially if the engine fitted is potent enough.

Dual side exhaust

Just as its name implies, it means the two exhaust pipes are placed beside each other on one side of the car.
