Let's say you're going along at 30 mph in third gear and decide to punch it: You immediately hear the exhaust note get seriously deeper and louder, along with an increasing rush
of air noise starting to bellow from the massive air intake.
Adding air deflectors / vent visors around the windows helps keep
the air noise to a minimum when the windows are open.
There is a lot of road noise and
air noise this car is in no way a quiet ride.
