  • Constant velocity muffler assembly
    Patent number: 11898474
    Abstract: A constant velocity muffler assembly for maximizing the exhaust performance of an internal combustion engine includes a muffler that is fluidly coupled to an exhaust pipe of an internal combustion engine to facilitate exhaust gasses to pass through the muffler. A cylinder is disposed within the muffler and the muffler swells outwardly at a middle of the muffler to accommodate the cylinder. The cylinder is oriented to extend along a flow axis of the muffler with respect to the exhaust gasses. In this way the cylinder is configured to deflect sound waves from the internal combustion engine thereby reducing a noise level of the internal combustion engine.
