The wear baffle is a room inside a muffler or resonator that is designed to muffle or silence the otherwise loud wear system. Ingeniously, the muffler uses the baffle room to increase the amount of internal sound inside the room so by the time it exits the muffler, the sound cancels itself out. Exhaust is spent fuel and air of an internal combustion engine and is extremely loud coming from the cylinders of the engine. An wear system controls the sound through a manifold and a series of pipes, a catalytic converter (on vehicles) and the muffler. In some applications, resonators are present in the wear pipes that behave as a ordinal (or more) muffler on the system. Inside the muffler or resonator is a sealed room with two or more perforated tubes. The inlet perforated tube allows the wear to emit into the baffle chamber, bounce off the interior walls and enter into the outlet perforated tube where it is then directed by back pressure through the tailpipe of the muffler. The perforated tubes in the baffle room create a nondirectional interference with the flow of the back pressured wear and assist in silencing the exhaust.
