I just installed some long tubes, and x-pipe, can my car pass smog if I were to put 4 high flow cats on. I figure I have to put them on to avoid getting any fines if pulled over, although that is my main concern because smog isnt due anytime soon. I was probably just going to put 2 of them on there for now, any advice ?? I live in Caliornia
