I don't think anyone would notice at a smog place. What I wonder is that if you remove the cats the car's ecu will detect exhaust differential that might throw an out of range error code. All 1M s are smogged via the OBD port and off the ecu reports something out of range, it will fail. It might not also? That's why I'm hoping to find someone in cal that has passed smog test with it on. Thank you
