A tailpipe is a component of a vehicle's exhaust system that directs exhaust gases away from the engine and out into the atmosphere. It is typically located at the rear of the vehicle and is designed to reduce noise and emissions produced by the engine. The tailpipe helps ensure that harmful gases, such as carbon monoxide and nitrogen oxides, are expelled safely. In addition to its primary function, the tailpipe can also affect a vehicle's performance and fuel efficiency. Different designs, such as those found in performance cars, can enhance exhaust flow, potentially improving engine output. Regular maintenance of the tailpipe is important to prevent rust and blockages that can lead to increased emissions.
