While your car engine is working and burning up gasoline, it is constantly releasing waste gases. It needs an outlet to make sure that these gases do not build up inside the car and are released safely into the atmosphere. This is where an exhaust system plays an important role. The exhaust system is attached to the engine and it extends to the back of the car and its main purpose is to release these gases into the atmosphere.
Depending on the car make, exhaust systems come with different fitment requirements. This applies across all kinds of car parts. Ford Ranger parts will be different to Ferrari Testarossa parts. Similarly, a Audi A6 exhaust system has different requirements for installation and mounting than a Holden Adventra exhaust.
There are four main parts of an exhaust system, these are, the manifold, the catalytic converter, the muffler, and the exhaust pipes. The exhaust manifold is the beginning of the exhaust system and is directly connected to the combustion engine. The manifold is mostly made of cast iron and is made in such a way that it collects the gases from the multiple cylinders and lets them flow into a single pipe.
Although the manifold is usually designed to be lightweight, the pipe lengths may be varied to improve the flow of the exhaust gases. In this case, it is usually called a header.
Once they flow into a single pipe, they move into the catalytic converter. The purpose of the cat converter is to make the emissions safer for the environment. Combustion tends to release various harmful gases. These include nitrogen gas, carbon dioxide, water vapor, carbon monoxide, hydrocarbons, and nitrogen oxide.
When these harmful pollutants pass through the cat converter, they are converted into less harmful ones before being released into the atmosphere. This simple device also makes sure that there is no smell of gasoline when the gases are released. Most racing cars do not have a catalytic converter, and have a less restrictive muffler. This makes them louder and generally allows the engine to liberate more power.
The cat back part of the exhaust system starts at the end of the catalytic converter and goes on till the final pipe. The pipe that connects the cat converter to the muffler is also included in this portion. In a racing car there is usually a straight pipe in place of the catalytic converter. Some fuels used in racing, such as Avgas (aviation fuel) contain lead which affects the converter's ability to operate. A muffler may be used to restrict noise to acceptable levels (for example 90 decibels, but if that's not required then having no muffler allows the engine to breathe more freely.
The basic purpose of the muffler is to reduce sounds by reflecting sound waves that the engine produces. It is a set of tubes with holes which reduces the intensity of sound by adding two or more sound waves together.
The sound and gases enter the device through the center tube. As it passes through the resonator, a wave is produced that cancels out a specific sound frequency.
Then comes the exhaust pipe. An exhaust pipe can be made of aluminum or any metal. It is designed to make sure that the noxious gases are taken away from the car engine and into the atmosphere.
In some case, the pipe may have chromed tip with a larger size than the rest of pipes. Besides preventing rusting of the edges, this chromed tip and larger pipe further reduces pressure and also improves the appearance of the car.

Before you buy a Holden for sale talk to people to get an idea of how easy they are to modify, particularly if you are planning a modified exhaust for racing. Get a vehicle history report before you hand over any money.
