Wait a minute!.. you can pass smog check with I/h/E?! All it has to do is not have the CEL. That's blastfumy.. I want to know about this shop because I'm about to throw money at him.

Gut or header route does if you're throwing the CEL, otherwise if the guy doesn't know what he's looking at (visual inspection) and their scanner checks out okay (running an O2 emulator if you're catless) then you pass. That's at least what someone at a smog station told me very recently.

Gutting the headers would probably be the everyone's best bet because if you get an O2 sim and put the stock cat back on for smog checks I feel like you should pass easily

this is the route i went down. i considered headers, but cost of headers plus paying to swap back to stock and back to aftermarket headers every 2 years is a costly venture.

The key here without cats is A) not having a check engine light w/o2 'Ready" and/or B) having a visual friendly tech.
The PPE o2 conditioner feeds the o2 sensors good false data and therefore they will 'Ready' state. If the car was tuned with a flash and the o2's disabled then you wouldnt get a light either, but the SMOG computer would see the o2 sensors as in a 'Not Ready' state and trigger an auto fail.
I think, that if you guys with IHE had to smog, swap in the midpipe with the two factory cats and you should be cool with a visual and technical. The reason being is the cats in the mid pipe would be visual to a mirror check and the header cats are hardly seen to begin with. The electronic o2 conditioner will take care of the o2 sensors, I wouldnt trust the mechanical o2 anti foulers. Fact is if you own PPE headers they include the o2 conditioner as a solder in part to the ecu wiring.
Its been a while but sikky headers electronic o2 unit was a simulator instead of conditioner, similar to turning off the o2's from reading. The main trick here is that the o2 sensors need to be tricked into 'Ready' when the state computer reads them from the OBD2 port.

This is interesting info. I am heavily considering doing the novel headers and they have mechanical o2 conditioners. Are you saying that I should also get the PPE conditioners to run on top of that? Does RR racing have a tune that leaves the o2 lines open so that they can display ready?

if I am understanding this correctly, with any headers (PPE, SIKKY, NOVEL) the key is to use conditioners to pass the OBD test, I noticed RR Racing sells conditioners on their website, any difference between those and PPE ones? In the Sikky V2 installation video, James used conditioner so I think Sikky is now also going with conditioners not simulators.
