personally , exhaust cat back , unless you want to go sports cat , sports cat in the real world don’t make a massive difference in performance but boost noise is quite nice , fuel pump , induction is a no for me do to constant noise plus apparently minimal increase in power , then a remap , the tmic seem to be good for big power , are your injectors going to flow enough depending on level of power on remap

Agreed, Ask your mapper he may insist on X or Y from experience.

i would assume, if UK car a min of Cat back exhaust, PF7 plugs, Remap. fuel pump unless already done with PPP. maybe injectors !!

The standard airbox will be on its limit at the power an MD321T is capable of.

Intercooler really depends on your plans. The STI TMIC should be ok with the MD321T for short blasts. However if you're planning a lot of track time or sustained periods of WOT then FMIC is the way.
