How Does The Coffin Muffler® Work?
Exhaust enters the muffler, and it passes by the "primary vein". Exhaust passing by the primary vein creates a "venturi", (a venturi is a constriction in a tube designed to cause a pressure drop when a liquid or gas flows through it, which results in an increased velocity), between the primary and secondary veins". This increase in velocity between the first and second veins, result in exhaust gases from the vehicle, to speed up the flow through the muffler. As the exhaust continues past the secondary vein, it is able to enter the area called the "resonation dampening space". This space allows both sides of exhaust flow to have the exact same sound tone as it passes through the outlet end of the muffler. When these events take place inside the muffler, the end result, is a muffler with greater flow capabilities, more aggressive sound, better horsepower, and better torque for the vehicle.
