Think it's regardless what car make it is? If the exhaust noise is >95db iirc, they'll get you for that (and we know the cars like the c63 amg's are not quiet cars on WOT so not sure how they even rollout of the dealers)
Do you have the wireless flap controller on your Akra? Just keep it closed and you should get through?
Sucks that EPA is spotting and issuing notices. Not good news for me when I'm planning to put on the BMWPE for my ride
Let us know how you go.
