Pretty much all of Stillen stuff and then Nismo Catbacks are 100% safe picks. I know a local dealer that orders and installs both, and I'd assume many do in the state.

CBE, once you clear sniffer and noise testing, still depends on the tester. Some will be uptight and actually look into CARB regulation, though from the sound of things, that's pretty rare. Like you must've picked the worst spot to get tested in that situation.

:iagree:

i passed smog w 300 cell BERK HFC

Two years ago I passed smog with FI straight pipe CBE but had to take my injen intakes off since had no CARB sticker. I would of passed this year with this set up since I received CARB certifications for my Injen intake. Keeping my fingers crossed for this year since I'm stillen charged. Gotta love the CARB sticker tho.

Stickers are so easy to make. Many shops will do it without checking anyway. Only boy scout owners will actually check.

i just moved to san francisco and im about to ship my car here from houston. I have test pipes so its not legal there either but all they do is plug into the obd2 and get readings - i have all my readings cleared so they cant pick any of that up and it passes. I heard they only do sniffer if its older than 2000? they do other stuff here other than plugging into the obd port?

There is a visual test for smog
