ABSTRACT:
A muffler may comprise a casing having an internal volume, an inlet and an outlet, and a diverter plate dividing the internal volume into a first chamber and a second chamber. The diverter plate may comprise a baffle wall portion and at least one diverter having a deflecting surface oriented at an angle to the baffle wall portion. The baffle wall includes at least one aperture allowing fluid communication between the first chamber and the second chamber. The diverter is preferably suspended with respect to the casing, wherein no portion of the diverter directly contacts the casing.
