If fitting a decat and decent exhaust system I take it you'll be re-fitting the OE cat for MOTs? May pay to buy a sports cat from the off and it'll be ready for the MOT. As said a free flowing exhaust will release the difference, but give the ecu time to part learn the changes. Manis is one mod I have not done as the remap was cheaper for the near on same figures. Torque being the bigger improvement from the graphs I have seen.
