Has your four cylinder grown to sound more like a throbbing V8? Chances are you are creating more than just noise pollution.

A car’s exhaust system serves a few purposes, the most important is to control and reduce emissions from your car into the environment. The second is to reduce another kind of pollution, that is noise. 
There are several ways to tell if something may be wrong with your exhaust; your car is making rattling noises, the exhaust is louder then usual, your car is producing smoke from the exhaust or, your exhaust smells odd.

Exhaust systems - everything you need to know and more

The exhaust system of a vehicle is a complex beast. The process starts near the engine where manifolds connect to the cylinder heads and collect the gases created by the engine. These gases then travel through a series of pipes until they reach the oxygen sensors, which determine how the catalytic converter treats the gases to make them more environmentally friendly. They then travel through the muffler, which makes them quieter. 

Oxygen sensors
The oxygen sensor is a small electronic device that is located in the combustion exhaust manifold of a modern vehicle engine. It is designed to detect and measure the amount of oxygen that is being expelled in the exhaust gas and send this information to the computer control unit, to tell the catalytic converter how to treat the gas.
Read our article about oxgen sensors if you wish to learn more.

Catalytic converters
The catalytic converter is designed to convert toxic gases into more environmentally friendly by-products.
Conversion of exhaust gases begins after reaching an operating temperature of approx 200 degrees celsius. The optimum operating range is usually between 400 and 600 degrees celsius.
We also have articles with more detail on catalytic converters and the diagnosis of catalytic convertor problems.
