I read online you have to have the supercharger be built for the model and year of your car including having the C.A.R.B. number and a sticker on your car. This also has to pass smog. I was planning to change my exhaust and header too (which I read on line might fail me on my smog check). Does anyone have any advice before I take the larger leap forward and saving all this money for this supercharger in CA?
