Bugatti Veyron w/ Mansory Exhaust vs Bugatti Veyron Grand Sport

I had the opportunity to film not 1, but 2 Bugatti Veyrons during a great supercar event. The blue/grey Bugatti Veyron is fitted with a Mansory Exhaust, the Bugatti Veyron 16.4 Grand Sport is stock. The Bugatti Grand Sport is the topless version of Bugatti's 1001HP 16.4 Veyron masterpiece.
