TRD makes exhaust, drop in air filter, oil cap, high pressure radiator cap, oil filter, thermostat, full suspension, and there is a factory aero kit you can pick up, as well as the optional BBS wheels.
It's too bad you missed out on the 1MZ-FE; there is a TRD supercharger for that (it was the V-6 for the first part of that generation of Camry (I believe)).
I personally think the oil and radiator caps look baller:
The TRD radiator cap is towards the upper left, thats the TRD resin oil cap and below the header is the white (U.S. spec, the Japanese one is red) TRD oil filter.
