An exhaust system is a series of pipes and components in a vehicle that directs harmful gases away from the engine and out of the vehicle. It typically includes parts like the exhaust manifold, catalytic converter, and muffler. The system helps reduce emissions, improve engine performance, and minimize noise. The primary function of the exhaust system is to safely expel gases produced during combustion. By filtering and treating these gases, the system ensures that the vehicle meets environmental regulations and operates efficiently. Regular maintenance of the exhaust system is essential for optimal vehicle performance and longevity.
