NH state inspection question

I searched and couldn't find anything specific to NH, so here goes:

I just got test pipes from Turner, and the ESS flash tune is on it's way. I'm going to leave the secondary cats and the rest of the exhaust alone, just going stealth mod for a bit more power. It shouldn't sound much different than stock and the flash will take care of the CEL. Does anyone know if NH actually tests the exhaust gases, and if so, if the primary delete will fail the test if I leave the secondaries and everything else alone?

Any help or insight appreciated. Also, anyone have a good shop to get the test pipes installed and the car inspected?

Few shops do a visual, few know what to look for on a BMW when they do, and none do a sniffer test.
