A device is provided for discharging two gases from a vehicle to ambient air, one gas having pressure pulsation of a first magnitude. The device includes an elongated body connected with the vehicle and having a first inlet connected with a first gas source, a second inlet connected with a second gas source, an outlet fluidly communicable with ambient air, and an interior mixing chamber, the two inlets being fluidly communicable with the chamber such that the two gases flow into the chamber. The body combines the two gases within the mixing chamber to form a combined gas having pressure pulsation of a lesser, second magnitude and to discharge the combined gas to ambient air. Preferably, the body includes an outer tubular member having the first inlet and the outlet and an inner tubular member disposed within the outer member and including the second inlet and a plurality of ports.
