Do these pass the emissions test and what is the result with regards to cell. I originally read they don't through cell? But now i have been seeing that they do or could do?

If they do through a cell can it be coded out with bm3 when running at stage 2?

Stone Eddy catted downpipe and Supersprint are the only ones I'm aware of that will not cause CEL. They're, at least,twice as much as anything else, though.

I have been driving around with this one for a couple of weeks now and no warnings.

(And quite a lot cheaper.)

Have driven with the Wagner 200cpi for around a month and a half now, very happy with it, no CEL after around 2500km driven.

Haven't checked the emissions part yet, but I am hopeful.
