Exhausts Repair

Acton Service Centre supplies and fits part or complete exhaust systems for any make and model of vehicle.

The role of the exhaust system is to guide the gases generated by engine combustion to the outside of the vehicle. Besides, it reduces noise, as well as the rate of pollution.

The exhaust system is important and one of the hardest working components of the vehicle. It is made up of:

• Manifold; connected directly to the engine cylinders and channels gases into the exhaust system.
• Lambda / Front Downpipe; an electronic device that measures the amount of oxygen in the gases as they travel through the car. The downpipe is where the gases merge from the engine into the catalytic converter.
• Centre Section; Includes the catalytic converter which helps remove harmful and pollutant gases, and a silencer box that helps reduce engine and vibration noises.
• Rear Silencer Box; additional filters to further reduce engine noise and connected to a tail pipe that directs gases away from the vehicle.

The most common section to become defective is the rear silencer as moisture tends to gather inside the box and attacks the metal. This internal corrosion will often result in a hole, which causes the exhaust to blow. A defective exhaust will mean the vehicle fails the MOT test. Additionally, it causes excessive noise; thereby rendering the vehicle illegal which could lead to a fixed penalty fine. An unchecked exhaust may also result in fumes entering the car, which can be harmful to the driver and the passengers.

Catalytic Converters

Catalytic converters are now fitted to all cars registered after 1993 to remove harmful pollution from the exhaust gases. This expensive and high-tech component fits in the exhaust system and looks on the outside like a typical silencer box.

The catalytic converter is an integral part of the engine performance system, and sensors control the gases entering and leaving the catalytic converter. Their effectiveness is measured by testing the exhaust gas emissions. This is an important part of the MOT and service requirements on all cars today.

The catalytic converter can be damaged if the engine is not properly tuned and excess fuel or oils enter the component. If your catalytic converter or exhaust does become defective and requires replacing, Acton Service Centre provides top quality replacement parts at a significant saving to dealer prices.

On a similar note, your car’s exhaust pipe also serves several purposes and should be maintained or replaced to get the best mileage possible and also to reduce the co2 emissions of the car.

How does the car exhaust work?

The work of the exhaust is to collect the harmful gases released by the combustion of the engine and send them to the particulate filter. The filter then works to reduce the harmful particles in the gases to the highest possible extent to reduce its effect on the environment. The gases then enter the catalytic converter to go through the chemical reaction to further reduce the toxicity.

Symptoms & results of a faulty exhaust

• Constant loud noises
• Exhaust fume smell
• Loss of power or lower functioning
• Lower mileage
• Clunking or banging from underneath the car

The effects of exhaust damage

Apart from an uncomfortable drive and unnecessary noises, a defective exhaust can be the reason to fail the MOT test as it is not considered safe for road use. It also is very harmful to the environment as the CO2 emissions are higher than usual with a faulty exhaust.

At times, the fault is visual and you can spot the damage which needs to be repaired. At other times, the damage can be hidden from the view as the exhaust pipe runs across the entire length of the underside of your car. To recognize the issue, your car will need a hydraulic lift.

In some cases, especially in older cars, rust can be a cause of concern.

Depending on the type of fault, driving with a faulty exhaust can lead to a traffic offence and is dangerous for everyone. Come in for a quick repairing and servicing of your exhaust fan at Acton Service Centre.
