If you are a high rev driver,I think akrapovic exhaust and KN 69 induction kit will do you just fine.
What do you think I'd gain in power and torque?
Akrapovic is nice, I've got some friends with e92 M3 with Akrapo exhausts (check out the vids here: www.youtube.com/user/vdvpj;
a red one and a blue one, both with performance parts)
