Obviously at least one of those cars isn't stock. The mustang's cowl hood? and exhaust tips suggest an exhaust system? Who knows what else. Lets read the mods for each car before judging this as a stock GT beating a stock SS.

Put a 5.7Liter in the Mustang while you're at it to keep it even. Plz no mo re dumb comments!

Hook a half ton trailer to the mustang, then maybe it'll be a fair race lol .
