Exhaust Systems

Automotive exhaust systems are an essential safety part of your vehicle and play a vital role in the performance, fuel economy and operating systems governed by many emission control regulations.

The components of an exhaust system vary considerably depending on the manufacturer's and country's requirements.

Its primary purpose is to reduce both the emission and noise pollution created by the everyday workings of your vehicle's engine.

While some components are common to both petrol and diesel systems, others are not, and diesel-powered vehicles often require a different approach to periodic maintenance and procedures to keep the system operating.

So what is the primary function of an exhaust system?

As your vehicle operates, the internal combustion engine creates explosions that push the pistons in the engine, creating the power we feel when the engine is operational.

This combustion process produces leftover gases and contaminants that need to be disposed of, this is the role of your vehicle's exhaust system components.

An exhaust system and its components must be in good working order to efficiently perform its role, whether redirecting gases to be fired again in the engine (EGR valve) or directing exhaust gases to the tailpipe.

The gases produced are dangerous to the human body, typically carbon dioxide, carbon monoxide, nitrogen oxides, and hydrocarbons. While we can't see these gases, we don't want them entering the engine compartment or cabin, so one of the main jobs of the exhaust system is to redirect these gases out the tailpipe at the rear of the vehicle.

With other components of the exhaust system, in place to reduce noise and harmful emissions entering the air around us.

With two basic types of fuel systems in use, Petrol and Diesel, exhaust systems are designed to suit each fuel system and process the leftover gases and carbons each produces.
