Ok, first question, i have hooker longtubes currently in the process of getting coated. I thought originally that longtubes would of been emmision legal in CA, but ive been reading threads and i guess their not? Even if i run the cat and muffler it still wont pass? Im a little confused?

Second question, how many o2 sensors are there? I thought there were only 2. And, how much do they cost?
