Hi, I searched and didn't find answers to this question. Has anyone in California passed the rolling dyno emissions test with the Sikky headers installed and header back exhaust with high flow cats (Joey Z, Borla, etc.)? I'm not worried about the visual emissions testing but rather whether the rolling dyno at 15 mph and 25 mph passes emissions levels with high flow cat and headers?
I would think so, if the car is running fine and there were no ECU modifications, but wondered if anyone has actual experience with passing numbers? Thanks in advance. For the Sikky (or other IS-F headers?) does it come with a CARB EO packard or sticker on it.
