When mine was n/a i had both cats removed, hks filter with custom heat shield, custom intake pipe which got rid of the 2 silencer boxes in the stock setup, uprated fuel lines and high flow fuel filter and removed the viscous fan and replaced with a electric one.
All this made a big difference imo to the cars performance but dont be expectting mega power gains from it. As much as people suggest buying a tt i actually like my n/a motor wich is why i kept mine and have just fitted a turbo to it.
