hey i just got a new 92 civic cx with ajdm d15b. I am not sure of the ECU because i haven't checked. i know it has a skunk2 intake manifold but it is california CARB legal. and has the stock tailpipe.and i'm also pretty sure it has a cat can,t really see because its lowered but i will check later. my question is what do i need to do to make it legally pass smog if i can get past the visual part?
