Abstract: In one exemplary embodiment, an exhaust dilution and dispersion device for a vehicle can include a generally elongate tailpipe comprising an inlet section capable of being in exhaust receiving communication with an exhaust system of a vehicle. The tailpipe further comprises an outlet section in exhaust receiving communication with the inlet section. The outlet section can also comprise a downwardly directed exhaust deflection portion and an exhaust outlet in exhaust dispersing communication with the surroundings external to the device. The exhaust outlet can comprise a generally elongate exhaust dispersion opening extending in a lengthwise direction along the tailpipe. At least a portion of the exhaust outlet can be coextensive with the downwardly directed exhaust deflecting portion and a major portion of the exhaust dispersed from the outlet can have a transverse component.
