Abstract
A muffler includes a shell, baffles, and a plurality of pipes. The shell defines first and second end cavities and a central cavity. The end cavities have larger cross-sectional areas that a cross-sectional area of the central cavity. The baffles cooperate to form multiple chambers within the shell. A first inlet directs a first portion of the exhaust into a first chamber. A second inlet directs a second portion of the exhaust into a second chamber. A first pipe extends through first, third and fourth baffles and includes an inlet in the fourth chamber. The first pipe directs exhaust from the fourth chamber to a first outlet at the first end cavity. A second pipe extends through the second, third and fourth baffles and includes an inlet in the third chamber. The second pipe directs exhaust from the third chamber to a second outlet at the second end cavity.
