Catless downpipes and NY State Inspection

I posted this on my local Z4 facebook group but no one had a decisive answer. I would like to know if anyone in NY state has installed catless downpipes on a Z4 with the N20 engine, and have been able to pass the NY state inspection process. One person said it could be done on a n54/n55 with a MHD stage 2 tune. I would love to make this mod, but having to back it out annually for our inspection just isn't worth it. If I could combine it with the right tune(s), that would be ideal. Has anyone out there done this?
