An exhaust pipe is a crucial component of a vehicle's exhaust system. It channels harmful gases produced by the engine away from the vehicle and into the atmosphere. This helps reduce the buildup of toxic fumes inside the car, ensuring a safer environment for passengers. The exhaust pipe is typically made of metal and is connected to the catalytic converter, which helps convert harmful emissions into less harmful substances. Proper functioning of the exhaust pipe is essential for vehicle performance and compliance with environmental regulations, as it plays a key role in reducing air pollution.
