The Magnaflow Street or the stock exhaust are you best options.

I have headers no cats with this setup and my car is very quiet at idle and part throttle with no drone or resonance and I have an A6. It does have a nice deep tone at WOT but not enough to attract unwanted attention.
You could also choose to purchase an S-Type Axle back and swap out the rear section of the ATAK.
