'If' you could just scrape through the emmisions test, you didn't need the cat (unlikely though with a dirty petrol!). Now the presence of a cat is checked on petrols.
For diesels, you still do not need a cat to pass as I asked vosa when I decatted. There is no diesel emmisions test, and cat presence isn't checked. You do need to pass smoke density test....but its gotta be really smoky to fail lol!!
