Device in the exhaust system of automobiles and motorbikes. Gases leave the engine at supersonic speeds. The exhaust system and muffler are designed to slow them down, thereby silencing them.
Some mufflers use baffle plates (plates with holes, which disrupt the airflow): others use perforated tubes and an expansion box (a large chamber that slows down airflow).
