Now, that original smog check was interesting, and it looks like it is the way all smog checks in California will be done. No tailpipe sniffer, they just plug into the OBDII port and read various settings, check for codes, and see what the ECU has to tell them about smog.
But it's more than just checking for OBDII codes, the modern ECUs actually are able to report on various smog related readings, more intricate/complex than just codes.
Bottom line: you will definitely fail with catless downpipes, you will probably fail with the catless midpipes (maybe, maybe not), but once you fail once, you will likely get flagged in the system.
So, what I would do is put the entire stock system back on, and then after you get your smog certificate, happily mode away, for at least the next five years.
