Hello fellow Ferrari owners, I need you help with something that my car needs. I live in California, smog laws crazy around here. I have read mixed reports about Check Engine Light coming on after Header's on F430 are replaced to fix weakness in stock headers. I am looking at Capristo Exhaust Headers to replace, but worried once I spend the money on them I will get a check engine light because they do not have the factory pre-Cats. A salesman said I would have no issue that it is rare to get a check engine light? Of course he is trying to sell them to me. What are you guys replacing your headers with in California? Any problems with check engine lights? Anyone use Capristo? What headers did you use? Much appreciated anyone who can respond with some experience, I don't want to spend 6k and then not be able to get car smogged.
