Exhausts, Dorking, Surrey
Your car’s exhaust is designed to help the vehicle run smoothly and quietly, as well as keeping it in check with strict government pollution and emission laws. When in operation, the engine will take what it needs from the supply of fuel and air, but this creates gasses that need to be allowed to escape. This is where your vehicle’s exhaust is vital.
How does the exhaust work?
The exhaust system is responsible for channelling and cleaning six gasses produced by the engine. Three of these are toxic:
- Carbon Monoxide
- Nitrogen Oxide
- Nitrogen Monoxide
The process is as follows:
- Firstly, the gasses are collected by the exhaust manifold and sent collectively down the front section of the exhaust pipe.
- The gasses are then sent to a section called the catalytic converter. This converter is responsible for cleaning and filtering these gasses, making them less toxic and less harmful to the environment.
- Once through the converter, the gasses are send through a series of pipes contained in the back box, or silencer.
- These pipes reflect the sound waves produced by the engine so they cancel each other out, reducing noise.
- The remaining gasses then pass out of the tail pipe, carrying them away from the vehicle and the passengers inside
How does my exhaust go wrong?
Usually, the main reason an exhaust will fail is rust and corrosion. With the exhaust being under the vehicle with no protection from the elements, unfortunately, over time, it will start to rust and corrode.
Many exhausts will last for a very long period of time and never require attention, but when exhausts are made of a lesser grade material or much older, they can suffer. Most commonly, holes will appear in the rear silencer of the exhaust, rust and corrosion can break joints and clamps holding the exhaust together, and also snap the hangers that attach the exhaust to the body of the car.
How much does it cost to replace my exhaust?
Because the exhaust is made up of 4 integral parts, there is a possibility that more than just the damaged/failed part could need replacing. Over time, the pipe work can fuse to the catalytic converter/silencer, meaning they have to be cut apart. It usually proves to be more cost effective to replace parts together, rather than individually, as the existing parts could cause damage to the new parts being fitted.
