Abstract
An exhaust component includes at least one muffler that has an inlet and an outlet. One pipe body is connected to each of the inlet and the outlet. The pipe bodies each have first and second ends that define a respective overall pipe length. Each pipe body defines a sole exhaust flow path between their first and second ends. A passive valve assembly is mounted outside of the muffler and within one of the pipe bodies. The passive valve assembly is positioned at a location within a first 25% of the overall pipe length of one of the pipe bodies relative to the inlet or outlet of the muffler.
