A vehicle should fail if it was built with a cat which is subsequently removed.
If you present a vehicle for MOT as running on gas, it will have emissions tested at idling speed rather than fast idle which can highlight other issues. For one of my vehicles, I know from experience it will fail emissions test when running on gas (due to the different test criteria used), but it will fly thru on petrol. When I had the LPG system tuned to give perfect emissions, it was completely gutless so the mapping had to be tweaked to give the best compromise in terms of performance and economy.
