The exhaust system of a motorcycle is a set of tubes that is attached to the internal combustion engine. When gasoline is burnt, waste gases are made. The exhaust system releases these gases from the engine and into the atmosphere.
The different motorcycle makes have different types of exhaust systems and they may come in varying sizes as well. This is also true for cars. A Mazda RX7 exhaust has different mounting brackets than a Kia Sorento exhaust, and the same logic applies, e.g., across Ford Escort parts versus other Ford or Holden parts. In terms of a bike, the muffler is more of a standard fitment part, whereas the exhaust is usually made specifically for the motorbike.
The exhaust manifold and the exhaust pipes are the two main parts of a motorcycle's exhaust system. The gases also pass through the catalytic converter and muffler before reaching the exhaust pipes. The manifold is the first part of the system and it collects the gases from the multiple cylinders present in the engine. The gases then flow into a single pipe, ready to pass through the catalytic converter.
Exhaust manifolds are usually not too heavy and small in size. However, often the lengths of the pipe are planned in such a way that the focus is more on enhancing the flow of the gases rather than it's weight and size. In this case, the manifold is called a header.
The catalytic converter is the next part of the exhaust system and its purpose is to make the gases less polluting and less harmful to the environment. The engine tends to release various harmful gases including carbon dioxide and carbon monoxide.
When these harmful toxins 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 you do not smell any 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 80dB, 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 exhaust gases and the sound waves enter muffler through a central tube. As it passes through a resonator, a certain frequency of sound is canceled by the wave produced in it.
Then there is the exhaust pipe. An exhaust pipe can be made of aluminum or any metal. It is designed to make sure that the poisonous waste gases are taken away from the 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 motorcycle.

An aftermarket exhaust frees up the flow of gases from the engine and enhances the performance of a racing vehicle. Before you buy a used Subaru it's important for you to get a good idea about how easy they are to convert for racing before you go out and purchase one for yourself.
