The exhaust system is a normally a piping system that is used to evacuate the ignition gases that are produced inside the ignition chamber. These gases are led through a network of pipes to the outside. The components of an exhaust system are:
1) Manifold or header
The manifold is an assembly of pipes that directly collect the ignition gases from the engine's combustion chambers. This is also called a header. The header is designed so each opening mates up with one of the engine's exhaust ports, and they are tightly sealed with the help of flanges which prevent the exhaust gases from escaping. From here, the exhaust gases are routed towards various other pipes and exhaust components.
2) Header-back
The header-back is the part of the exhaust system that is from the ending of the header to everything till the final outlet. Header-backs are used in exhaust systems which does not come with a turbo charger.
3) Turbo-back
In this case, the system comes with the turbo charger. A turbo-back is an aftermarket performance device that leads from the turbo charger to the outside.
4) Catalytic converters
Catalytic converters reduce the level of toxic waste in the ignition gases. For this, the insides of the catalytic converters are coated with different kinds of metals. Different types of catalytic converters use different combinations of platinum, palladium and rhodium. The gases that pass from the ignition chamber through the header contain super-toxic combination of carbon monoxide, nitrogen oxide and hydrocarbons. These are the chemicals whose presence is tested in an emission test for automobiles. When the metals inside the catalytic converter comes into contact with the gases, chemical reactions happen and hey reduce the toxicity of the gases. As the exhaust passes through the catalytic converter, the toxicity is reduced thereby satisfying environmental health issues.
5) Cat-back
Cat-back (also called as axle back) refers to the portion of the exhaust system from the outlet of the catalytic converter to the final vent to open air. This generally compresses of the passage from the catalytic converter to the muffler, from the muffler to the tail pipe and to the outside.
6) Muffler
One only needs to custom-remove the muffler and check what noises an engine produces. The noises that an engine produces along with other components are simply too loud and disallows any comfort for the passengers and the others. Thus, the muffler does a very crucial job. With some very simple but efficient acoustic techniques, it reduces the noises that reach it through the exhaust system to a very high extent.
7) Tail-pipe or exhaust
The tail pipe is the final part of the exhaust system. This is the exit for exhaust gases which pass through an array of pipes, gotten processed and muffled, to the outside. The tail pipe usually points towards the opposite direction to the direction of travel. However, this might differ in some cases as the tail pipe points sideways. The tailpipe is usually the only visible part of the entire exhaust system.
