That certainly was the case in the past with the whole 'blown diffuser' situation which led to cars' engine maps being specifically created to allow lots of volume of air through the exhausts even when they weren't generating much power to take advantage of this - listen to the exhaust sound in mid corner of this era F1 car and you'll hear what I mean (I think it was around 2011 and Red Bull were the best at it, but I think many did it to a degree).
