Catless downpipes

I need help again from the more knowledgeable members.
I'm wanting to buy some AR design downpipes but am worried that the catless option will have high emissions.
The car must pass UK emissions test (MOT) when it's due and I'm not sure if this is possible with catless DP's.
Does anybody know if it will fail the MOT with the second cats in place? or if there will be a big diffrence in emissions?
Please help!
