The exhaust system is intended to remove exhaust gases from the engine. As they contain a great amount of toxic compounds, exhaust gases must not get into the cabin. Moreover, the way the gases leave the engine has a direct say in the output. Without a properly-tuned exhaust system reliably carrying out its functions, the engine loses 10-15% of the power. Modern exhaust systems also have emission control equipment legally required in most countries. It includes catalytic converters, oxygen sensors, and EGR valves.
