Video: 2011 Shelby GT500, now with better sound!

A few days back we had a video featuring a 2011 Ford Mustang Shelby GT500 making the rounds at Virginia International Raceway, besting the '10 model's time by 9 seconds. While the video was nice, the sound wasn't the greatest. To correct this travesty, this new video has enough good noise to make up for the first.
