I would do some ECU work (ecutek or similar) and a turbo back exhaust.

Easy to net up to 30 - 40 hp from that combo.

3" TBE, EcuTek3 Tune, Fuel Pump. Will cost around $4500, but by far your best bang for your buck! Ring Race Torque

365hp and 515nm

New Beast to arrive April 2015 - 365hp, 450nm, 0-100 in 4.4sec. AMG Goodness!

that's great if you have an MY06 but if your MY02 up-pipe is stock then get ready to buy a new turbo as well !

Yep, just need to add a new up-pipe to that equation, and it'll be sweet.
