No downpipe in CA will pass the visual inspection if they look. It could pass the sniffer test if they administer it to cars this new (I actually don't think they do). But the answer is almost always no for the visual. That being said, you could find a 'friendly' tester, or remove/reinstall stock DP for the test.
