Hmm interesting. Can't pass smog test could be hard.
They definitely pass smog test as they are still cats on them and will pass visual inspection. Also you don’t need to smog your truck until it like 7 or 8 yrs old. Sold my 17 gen 2 this year and never had to smog it in CA

The aftermarket cats absolutely do not pass visual and will not pass smog. With that said, honestly most shops will look under the hood and do an OBD scan and call it a day. So as long as you swap your stock intake back on and don’t have a huge fmic, they likely won’t take the time to look closely at the downpipes.

If it doesn't pass smog would have a problem for cali people. Which sucks. Maybe gotta wait, I can't imagine swaping them back just for smog check. Hmm
