Aftermarket Exhaust and smog test in california

[SimonC104]

Hey guys been looking for a while online and couldnt find anything other than people having to keep their original exhaust to swap in for smog checks.
Thats also for straight pipe guys also im guessing so wondering if anyone in the bay area or California in general have an aftermarket cat back exhaust and are you able to pass smog with the aftermarket or do you gotta do the swap thing or know a smog guy lol. I just dont want to have to go through all the trouble of keeping my sports exhaust and swapping it every 2 years for a smog check its just to much trouble.

Since the primary cats are still in place with any aftermarket system all you emission monitors will not be affected.
Visual inspection will not be possible since they cannot see the stock system to begin with.
