How do SuperTrapp mufflers reduce noise?
Sound energy in SuperTrapp mufflers is reduced in two ways: it is absorbed through a perforated core inside the body of the muffler, and it is diffused 360 radially as the exhaust passes through the discs. The number of discs used determines how much total sound energy will be absorbed and diffused. Fewer discs will have less open area and tone down the exhaust note. Most mufflers today reduce noise levels in several different ways, such as sound absorption, reflection using baffles or resonating chambers, or restriction. Physics tells us that air in motion does not like to change direction. Original equipment mufflers typically change the direction of airflow 90 to 180 several times as it passes through chambers or is deflected by baffles.
