Luckily for new cars California they extended the test exemption to 7 years. Though if you happen to get reffed by an asshole cop. Then you are screwed. The ST200 Airbox looks bone stock from the outside besides being shorter on the underside. Tech may not notice that as its not obvious from up top. As far as intake hoses go ? I just feel its cleaner to run something like the Mountune then hassle with swapping out evap lines making it more work to switch back to original stock.
