It's got manufacturer plates on it, but Hard to believe that cut out for the dual exhaust was done by a manufacturer for a prototype... hatchet job and they have access to far better resources than that.... looks like they did it with a large cut off wheel!
If anyone has a 2017 5.0 resonator they deleted and would part with for cheap, I'd be interested. I deleted mine and got rid of it, but would now like to return to stock.
