So does anyone know if you can pass smog in california without the muffler on a aftermarket exhaust? (borla catback) Ill be keeping the cats on Im just sick of scrapping the muffler on every **** driveway and speed bump. It hangs way to low.

If it is a CARB certified cat back system you should be fine as long as you installed the provided CARB E.O. # sticker somewhere under the hood. Without that little sticker you will likely not pass the visual part of the inspection even if the car still passes the sniffer or OBD II diagnosis it will still fail and you will not get your tags.
