So you fitted a decat Y piece, with tune resistor. You also took out the pre cats.
The important question is, did you remove the lambda sensors from the manifolds? Did they have lambdas in the first place?
You only need to turn the tune resistor from white to green if you have removed the lambdas, so the converse is true if you are putting the standard Y back in for MOT.
YHM shorty.
