Yes, they have the authority to stop You - You have to fullfill the legal requirements of the state, where you use Your car.

And they will stop You, that's for sure!

I was told this does not apply if you are just passing by. It would be impossible to adhere to all local state rules tbh. Same goes for drivers license, I dont have German one by the same definition I cant drive in Germany. Frankly does not make any sense. I have some friends that have tuned sportscars which I'm absolutely sure would never pass inspecton in Germany due to noise level, wheels, suspension and engine mods and they still visit Germany often without any problems. On the other hand with my car its a bit more obvious for people that know this stuff. We shall see eventually.
My car is registered as vintage and accepted by authorities as historical vehicle with non factory tire specs, exhaust high noise level and all that, basically classic period correct street/strip car. I actually put Flowmaster S10 on very short exhaust on the car for inspection and it passef with vfl exhaust so they put noise readings in the paperwork. Readings said over 100dB where 95dB I think is max here for normal car. This way I can get away with 3,5" exhaus and Spintech 3000 mufflers before the axle. At WOT its a nice music, here is some part throttle sound and idle:
