The consensus is 3" is optimal for performance. Keep in mind you will probably experience boost creep with such an exhaust. In fact if it's a S4 then you will probably need to take measures to combat it. eg. port wastegate.

2.5" -> 300hp
3" -> 500hp
3.5" -> 700hp
4" -> 1000hp
2 x 2.5" = ~4"
These are the approximate pipe diameter versus HP numbers I use as a rule of thumb.
All numbers are hp at the wheels.

It's a matter of what you can find under the car and how much you can afford to pay.
Exhaust pipes over 3" are not very easy to find or cheap.
