INSANE Straight Pipes Rev Battle! 458 Speciale, Granturismo, Panamera Turbo

Thanks to FLGNTLT, R3 Wheels and Messer Wheels, I was able to film that insane rev battle, during which I lost a bit of hearing... The loudest obviously is the Ferrari, with a V8 screaming until 9000rpm... But the Maserati has some voice too, and the Porsche the basses !
