That was one of the best car commercials I've seen. Awesome exhaust note on that car, couldn't hear the blower at all like you can on the Lightnings and Cobra's, that may have been touched up though.
The GT powersliding around that track was amazing.
There was no touch up. I saw it in person last year and it sounds that good no blower whistle. Although it dooesn't sound as good as the old gt-40with the 289 in it.( they drove both cars in at the car show )
