Greatest Sounding Mustang PERIOD!
 

Here is a video of an American Iron Extreme SN-95 from this weekend at VIR.
All I know about this car is that it is a 351, has Hooker Super Comp Headers, Homemade H Pipe and Borla Mufflers, some type of straight through design.
Anyways, here is a pic and a short vid of how sweet it sounded. Fly by was probably between 130 and 140 MPH. Sorry for the single channel recording:
