3.73's or weight reduction?
A light weight K-member, Light weight battery and a race seat will be very noticable especially since it's all from the from of the car.
I would do a converter first if you are an A4. Like posted above though, you might be better off doing the main bolt-ons first (headers, CAI, UD pulley and a good tune).
Good luck!
