Ferrari F1 Loud Sounds @ Imola Racetrack - Accelerations & Revs

Marco records many Ferraris F1 of the Scuderia Ferrari being driven at the Imola racetrack. The vid shows some of them accelerating very fast in the track, leaving a deafening exhaust note! At the end of the vid there are 2 of them revving up the engines, next to other F1s. There weren't only the new F1s, but also the classic, like the one of Niki Lauda.
