As I understand it, your options are :

- Pass inspection, install headers, enjoy for two years, put OEM headers back on, pass inspection, put aftermarket back on
- Pass inspection, install aftermarket headers, AND cats and have a tune done to accommodate the new cats.

Either way, it's going to be expensive to get headers on.
