Eveything you do to your car is legal as long as you do not drive it on public streets or don't drive at all. As long as you have valid emissions and inspection results you're free to do whatever you like. (provided that you get the emissions and inspections results before the mod.)
That's my understanding of the issue. Please, correct me if I'm wrong.

if you get a test pipe, can you run a BOV safely then?

if you live in a state that has Vehicle emissions inspections you need a cat. NJ does visual + OBD11
