ABSTRACT:
A fairing is configured for use with the exhaust stack of a heavy-duty vehicle. The exhaust stack has an exhaust pipe with an intake end for receiving exhaust gases from an internal combustion engine and a discharge end for discharging the exhaust gases. The fairing includes a streamlined exterior surface and a cavity for receiving the discharge end of the exhaust pipe. An aperture extends through a rear portion of the exterior surface so that exhaust gases discharged from the discharge end of the exhaust pipe pass through the cavity and out of the aperture. The fairing further includes a coupler to couple the fairing to the exhaust pipe.
