A vehicle includes an engine generating exhaust gas flow and a vehicle body having a first body end facing oncoming ambient airflow when the vehicle is in motion and an opposite second body end. A vehicle underbody section spans a distance between the first and second body ends. A diffuser disposed at the second body end controls an underbody airflow portion past the second body end. An exhaust duct discharges the exhaust gas via a duct outlet arranged between the underbody section and the diffuser. A first diffuser aperture aligns with the duct outlet for discharging the exhaust gas from the outlet to the ambient. A second diffuser aperture pulls at least a fraction of the underbody airflow over the duct outlet and through the first aperture. The first and second apertures accelerate the pulled underbody airflow to increase a downforce on the vehicle body at the second body end.
