Thanks for the comments guys! I talked to Fabspeed, and did some more research into Kalifornia's arcane smog laws (and ooh what fun that is)..Fab says their system is Ca legal, but they do delete the aft cats, so technically it's not. They say the aft cats are not in the OBD-II loop (true), but to be truly CA legal they'd have a CARB cert, which they dont. As you pointed out, the reality is any drive thru smog station wouldn't know what to look for, and (as Fabspeed insists), the exhaust would pass the sniff test regardless. a crap shoot really, or reinstall stock muffler every 2 years...
