AFAIK the emissions test doesnt test for the gasses that are absorbed by the CAT anyway.

So as long as the tester can still see that there is a thing in which a CAT should be, whether or not a CAT is actually inside isnt something he can tell.
tester dont care ,u have CATs in or no,it will not pass emission test without them anyway
My E34 has passed emissions 2 years in a row without the Cats. NCT might be stricter.
