Other than carbon fiber? haha
An ECU tune can be pretty pricing with minimal gains. For exhaust I did the muffler delete which is cheap and sounds really good. Then I pickup a RPI air scoop, K&N drop in filter and a sprint booster (perfect to get rid of that throttle response lag). The OEM wheels are killer looking but they weigh a ton. If you can get lighter ones you will notice a huge difference in braking and accelerating performance.
Here is waht I did to the front of mine. Also did the CF trunk/roof spoiler and gloss black wrapped the diffuser.
