This will not pass smog in CA for two reasons.
Smog tests now test software levels...w the Cobb tune present, it will fail.
Next, CA smog laws require no change of emissions related equipment...your headers and "cats" are both not CA smog legal, and I have not seen that Dundon has a CARB approval.

- Use Cobb tuner to flash back to stock
- put back stock headers and exhaust for test and then put aftermarket back on after test
OR
- Find a smog guy in SD (if anyone knows one please PM me
)
