See - that's the real rub - "bone stock" means stock tyres and STOCK fuel tyep.
If the car is really running race fuel, then the real reason would be because they tweaked the tuning on the car and need the higher octane to prevent it pinging itself to death.

Turbo charged love hi octane fuel for higher boost and it less risky whit detonation.
So that gt2 could be pretty much stock only running race fuel or have a tweaked ecu but otherwise and i don't think that it has aftermarket exhaust because it sounds very much like a stock gt2
