Abstract
A muffler for a vehicle exhaust system includes a first outer shell, a second outer shell that cooperates with the first outer shell to define a muffler interior cavity, and at least one porous partition that separates the muffler interior cavity into at least first and second sub-cavities. In one example, the porous partition is integrally molded with at least one of the first and second outer shells. In one example, an exhaust tube extends through the first sub-cavity and acoustic fiber material is located within the first sub-cavity.
