Exhaust Replacement (free quote)
The exhaust system is an important component of your vehicle. Firstly, the exhaust helps to direct noxious gases away from the cabin, so you will not be exposed to gases that can harm your immediate and long term health.
Another important function of the exhaust is to make sure your car is being as fuel efficient as possible, by monitoring the levels of oxygen emitted and using this information to balance the fuel/air mix of the engine to the optimum level.
An exhaust is not simply a pipe to release waste gasses from an engine. There are various component parts that make up the exhaust system. You may have heard of several of them or you may have been diagnosed requiring a replacement part such as a catalytic converter or back box. We believe in educating our customers so please find on the right the component parts of the exhaust and their purpose.
Exhaust Systems
Exhaust Manifold
This is connected directly to the engine cylinders and is designed to take gases released from the engine cylinders and channel them into the exhaust system.
Lambda/Oxygen Sensor
Located in the front connecting pipe, this electronic device works with other sensors on the car to measure the proportion of oxygen in the gases as they travel through the car to determine and maintain the level of air to fuel ratio.
Catalytic Converter
This is designed to reduce the number of harmful pollutant gases as they travel through the exhaust system.
Centre Box (Middle Silencer)
This is connected to the catalytic converter with another connecting pipe. The box is lined with baffles which create acoustic filtering chambers to which engine noise and vibrations are reduced.
Back Box
This is the penultimate section placed to the rear of the vehicle and connected to the middle box with further connecting pipes. Similar to the middle box, baffles create more acoustic filtering chambers so engine noise is reduced further.
Tailpipe
Often part of the back box, the tailpipe will direct gases out of the exhaust system and away from the vehicle.
