Bassclly new I installed them on my 2011 Mustang GT and the Mustang that was totaled six months after I purchased it.
I’ve had them in my shed thinking I would get another Mustang, but that’s not the case so it time sell them.
There is light scratching on the top of the chrome tip from where the Muffler fit under the rear of the car which is normal however it would probably buff out.
I don’t know what else they fit besides a 2011 Mustang but if you use the model number to research it, I’m sure you can find out if they fit your vehicle
