New PX 125 MOT?

[whitepx]

Hi all, apologise in advance if the question is bit stupid, that's the first time I have a scooter in UK so I'm not sure about all the rules.

Just bought a new PX 125 and would like to change the catalysed exhaust for a 'normal' one, so in 3 years when is it time for the MOT do I have to put back the catalysed exhaust to pass it?

Thanks

in theory, yes.

in practice, no as we don't have an emissions test for scooters.
