You know there were and there are a lot of polemics about the blown exhaust system (EBD). Teams blowing their diffusers rely on the throttle being open to keep airflow passing to the diffuser and increase the downforce on it.
In this video you can hear how they sound like on different F1 cars. It's really particular listening to this kind of sounds but, IMO, you can get annoyed by this sound. I prefer listening to some nice backfires ;)

What do you think??
