so he is saying that the converters are illegal

Yes its an offence to alter the mileage of a vehicle, but your not doing that, your making the speedo give you a speed in mph instead of kmh. No one has mentioned altering the mileage of it, which I think everyone knows is illegal. It simply means that from when you fit it, it will clock up in miles rather then kms. Nothing illegal with that!
