Chip , DP, and a DV. Exhaust didnt do much for mine...the DP and chip def did! If I had ran slicks w/ chip only I'd hit 13s...almost did w/o. Do APR or GIAC whichever is cheaper.
I have a shaved (notchless) hood for a jetta 4, Plat gray ..$150 ...And some very clean 03 jetta OEM tail lights for $40
