:confused:SMOG HELP (Emission)

[KAredkouki]

sry for the stuff stupid questions but i am really confused. so this is whats happening. i passed all the eletrical ecu stuff for smog, but my emission too high. I am running on HotShot Headers and greddy extreme exhaust. Some people told me to put on the stock exhaust manifold and the stock front cat (down pipe). Then other people told me that to get a magna flow. So which 1 do i do? and if i do get a magna flow do i get the piece that replace secondary cat? and is the stock secondary cat hollow and the front cat is the 1 with the filter? thx guys
