I have a brand new in packages pair of Grimmspeed simulator to allow all track modes while leaving exhaust in Quiet or Sport to meet sound regulations at tracks. These only fit Shelby GT350s '15-'20. Ford changed the wiring on the 2018-20 Mustang GTs with active exhaust so they don't work for me. Asking $45 shipped, list is $60+ shipping from Grimmspeed.
Thanks
