These were on my car when we got it a few days ago? Are they Ford racing shelby muffs someone painted?? says 'made in the usa' and 'patent pending' on em..

yea I know the bracket is broken off too..

 

Yea, the broken bracket is common on the Ford Racing GTA mufflers. AKA Supreme Performance mufflers and they are used on Shelby GT's & GTH's. Which are what you have there and have as you guessed been painted.
