What Does the Exhaust Do?

The exhaust runs from the engine all the way to the pipe you see at the back of your vehicle and its main job is filtering noxious fumes and particles generated by your engine and directing them away from the vehicle. It also improves the performance of your engine, enhances fuel efficiency and controls noise pollution.

If there is a problem with your exhaust system, it may force your engine to work harder and fuel consumption will be increased. In addition, toxic fumes may not be converted and reduced and they may not be safely emitted. In severe cases, this could lead to noxious fumes entering the cabin of your vehicle.

Exhaust problems can be serious, so if you do notice any signs that it is not performing effectively you should visit a specialist as soon as possible.

How to Identify Problems

Although the exhaust system is located underneath the vehicle, there are some symptoms you can look out for which may indicate that there is a problem with your exhaust.
