What do the Ford Racing Stingers sound like? I will go on youtube and try to find out. I am really wanting the 2010 factory axle back because I am not wanting my Shelby loud like my 03 is. Kind of opposite of how I usually am but really like the Shelby stock just need some high flow cats and better flowing mufflers that aren't too loud so I figured the 2010 Shelby would be the way to go. Thank you very much for the offer and I will check out the sound of them.
