Exhaust repair and replacement specialists

The exhaust system on your vehicle is designed primarily to; to channel dangerous fumes away from the passengers inside of the vehicle, reduce noise levels generated by the engine, increase performance & fuel economy and help protect the environment.

Because they have to work under harsh conditions including the extreme heat developed by the combustion of fuel and the vibrations of the road, they can often fail over time. Failures include breaking down internally or rusting on the outer shielding.

Catalytic Convertors / CAT

To meet European standards most modern day vehicles come fitted with a Catalytic Convertor, also called a CAT, on the exhaust system. Its role is to convert harmful gases produced by the combustion of fuel to less harmful gases for the environment. They are usually made out of special expensive metallic materials can last upto 100,000 miles. Failure is usually occurs when un-burnt fuel enters the CAT and ignites, as the CAT runs at high temperatures. A vehicle that is misfiring or running rough is the common cause of CAT breakdown.

Lambda / Oxygen sensors

Vehicles fitted with a CAT also have one or more Oxygen Sensors, also called Lambda sensors. The sensor monitors the oxygen levels before and after the CAT and relays this information back to the Engine Management system which monitors and adjusts fuelling accordingly. The sensors are usually made with an internal heater which can become faulty. If there is any issue with the sensor, CAT, or major exhaust leak the Engine Management light will be indicated on your dash board. Manufacturers recommend replacing the Sensors when the CAT is replaced. Vehicles from 2002 require Type Approved CAT’s which are to made high manufacturer specification or better.

Diesel Particulate Filter / DPF

Newer diesel vehicles can be fitted with a DPF (Diesel Particulate Filter) which reduces the exhaust smoke that is generated from Turbo Charged Diesel engines. Most of the DPF’s have to be serviced by the use of additives, which can be carried out at our centres. Other vehicles require replacement of the filter every 100,000 km / miles. The onboard diagnostic system will alert you of when attention is required. Remember to use the correct oil on vehicles fitted with DPF’s, as the wrong oil can cause premature failure of the DPF and be costly to repair.
