exhaust pipe

The exhaust pipe is a crucial part of an automotive engine's emission control system. It carries combustion products from the engine cylinders to the rear of the vehicle. Along this path, exhaust gases typically pass through a catalytic converter, which uses catalysts to convert harmful pollutants like hydrocarbons and carbon monoxide into less harmful substances such as water vapor and carbon dioxide. The exhaust system also includes a muffler to reduce the noise produced by the engine's combustion process, transforming sharp sounds into a quieter stream of gases.
