2012 looking for Quad Exhaust: any advice for how it could be modified

[So Boss]

Hi,
I got minor rear end damage, which requires to buy new valance panel and exhaust muffler.

I'm not worried. I would like to take this as an opportunity to modify my 2012 Boss for quad exhaust outlets like 2013 Shelby.
Few questions:
-2013 Shelby exhaust mufflers seems to be bolt on?
-but 2013 valance panel seems to be so different that it cannot be modified to fit 2012, right?
-any aftermarket valance panel options to fit 2012 bumper cover?

I believe you need the GT500 rea valance panel also. They are a direct bolt on part. That's all you should need but I'm not an expert on that swap.

2013 Shelby GT500 AB Quad Exhaust Tips and Valance. Yes, this should work nicely.

Looking back now at the 2013/14 GT500, these cars are really sweet Mustangs. Last of the solid rear axle 662 HP Mustangs, I have to think about that for a moment. (If you know what i mean.)

Will have to keep my ear to the ground.
