    It checks up on the functioning of the catalytic converter using the 1st and 2nd lambda probes.

    i read several reviews saying i would not get a cel . is there way to fix this w rosstech? also in what mode does this put car or what map?
    are u talking about the O2 sensors? there is nothing else on the exhaust !.
    all reviews said no cel .
    how do they detect no cat? what reading is it, temp changes on the O2 ? I found 1 post you can install a 25mm extention then the O2 and will fix this.

    42draftdesigns O2 spacer .... Apparently their spacer works the best for getting rid of the cel code ....

    I know a friend who's catless and stock tune and he installed the rear O2 spacer and that got rid of the code so far ....

    As far as I'm concerned, the only correct way to solve this is by fitting a functioning catalytic converter...

    Why do you think it has 2 O2 sensors, one before and one after the catalyst?

    If they both read more or less the same, that means nothing happens in between which means the catalyst is not functioning.

    Is there any cat you can buy to replace the factory one other than another OEM unit that is qualified to ensure no emissions testing issues?

    I finally got a plug so I could back pressure test my cat via the O2 port. It ended up being no hint of back pressure, so my issue is elsewhere. Prior to that conclusion, I was looking $950 for a replacement cat (I also have a 2.0T) and that seemed nuts. Except every other option possible, with or without a stage 2 tune, is a crapshoot as to if a spacer may or may not address emissions readiness issues (ie, ready and no mil).
