That's from 3D Carbon. It's part of their Boy Racer body kit. I *think* it's pretty much the same as the 2010-12 Shelby. I don't know if you can get just the rear bumper cover from 3D Carbon. But I know you can get the Shelby part from Ford. Part number is AR3Z-17F828-AA and is $150 from Tousley Ford. I don't think you need the actual bumper cover - just the lower valance piece.
