Our good friend Marchettino has strapped a GoPro HD camera to the rear of a Pagani Huayra to give us a tail-end view of the supercar's square-shaped quad-exhaust pipes - the distinguishing feature of the Huayra's rear fascia - as the car roars around the track.

The experiment is intended to give us the track sound of the Huayra and we get that in spades here as the hypercar does a few laps around the Adria International Raceway.

Here's one case where the expression 'the sound the fury' is very apt.
