An automotive exhaust system is a series of components that directs harmful gases away from an engine and reduces noise. It typically includes parts like the exhaust manifold, catalytic converter, muffler, and tailpipe. These components work together to ensure that emissions are treated and that the vehicle operates quietly and efficiently. The primary function of the exhaust system is to manage the byproducts of combustion, such as carbon monoxide and nitrogen oxides. By channeling these gases safely out of the vehicle, the exhaust system helps improve air quality and meets environmental regulations. Proper maintenance of the exhaust system is essential for optimal vehicle performance.
