Will my car pass the MOT if I remove the catalytic converter?

I'm wondering if it is legal to remove the two catalytic converters from my car. It's a 2005 Audi A4 3.0-litre diesel. It has no DPF fitted from standard, just a primary and secondary cat. Can these be removed and still pass an MOT?

The catalytic converters are designed to reduce your car's harmful exhaust emissions. Removing them will increase the level of toxic gases that are released and result in the car failing the MoT.
