peräputken

Peräputken is a term of Finnish origin that literally translates to "tail pipe" or "exhaust pipe." In automotive contexts, it refers to the pipe extending from the engine's exhaust manifold to the rear of a vehicle, through which exhaust gases are expelled. This component is crucial for directing harmful gases away from the passenger compartment and reducing noise pollution.

The peräputken is typically made of steel, often coated to prevent corrosion. Its length and diameter vary depending on the vehicle's make and model, influencing exhaust flow and engine performance. Over time, the peräputken can suffer from rust or damage, leading to leaks, increased noise, or a reduction in fuel efficiency.

Beyond its automotive application, the term "peräputken" can occasionally be used metaphorically in Finnish to describe something that is at the very end of a process or line, or something considered insignificant. However, its primary and most common meaning relates to the exhaust system of a vehicle.
