Next to do on the 996

[M@1975]

just got the 996 back after having the engine thoroughly checked over, clutch replaced, RMS done, new IMS fitted, rear end polybushed and new engine mounts fitted.
I recently refreshed all the front end rubber bits too and just need to get some new tyres on it before getting the geo done properly.
With a clean bill of health on the engine despite the annoying tappet noise I'm very happy and it feels like a new car, question is what to do next? I've been toying with an exhaust upgrade, I have sports boxes on at the moment which I presume was something factory optional as it looks OEM but is not the PSE. Is it really worth doing a whole system upgrade from manifolds right though or is there something else I should spend my cash on?
I know people will say just enjoy it as is but I really want it to be as good as humanly possible and completely futureproofed.

Seagoon, I've had the same diagnosis as you. It's a real pain as the car has been thoroughly checked over and given a clean bill of health apart from the noise. It is on the list of things to do next for general maintenance but it is a lot of labour, the thought was to leave it until the next big bit of work and do the lot at the same time.

Might go with the larger throttle body, manifold and tubi combo as the next mods for the car and then do the CSF ally rad upgrade if I can find them in the UK.
