Abstract: An exhaust device (108) for a vehicle is provided. The exhaust device (108) includes an outer shell (202), an inlet (206) to receive exhaust gases, an outlet (208), an inner shell (204) received within the outer shell (202), a pair of partition walls (216) and a Helmholtz neck (220). The inner shell (204) defines an inner volume (210). A plurality of first circumferential openings (212) extending through the inner shell (204) fluidly communicates the inlet (206) with the inner volume (210). A plurality of second circumferential openings (214) extending through the inner shell (204) fluidly communicates the outlet (208) with the inner volume (210). The pair of partition walls (216) is disposed between the inner shell (204) and the outer shell (202). The pair of partition walls (216), the inner shell (204) and the outer shell (202) define a Helmholtz chamber (218) therebetween. The partition walls (216) seal the Helmholtz chamber (218) from the inlet (206) and the outlet (208). The Helmholtz neck (220) is disposed on the inner shell (204) or one of the pair of partition walls (216).

Abstract: An exhaust assembly includes a first tailpipe having an exit end and a curved portion along at least a portion of a length of the first tailpipe. The exhaust assembly further includes a baffle surrounding the first tailpipe at the exit end and defining a plurality of perforations therethrough. The exhaust assembly further includes a pair of shields. Each shield is attached to and at least partially surrounds each of the baffle and the first tailpipe. Each shield extends from a first end proximal to the exit end of the first tailpipe to a second end distal to the exit end of the first tailpipe. Each shield engages the baffle at the first end and engages the first tailpipe at least at or proximal to the second end. The pair of shields is adapted to allow fluid flow to or from the plurality of perforations of the baffle.
