Unfortunately no 4 pipe setup (miss-read your original post) - just a straight replacement with no bumper cutting.
Looks like this:
Be warned it isn't cheap though - I didn't pay for mine as it was already fitted!
It isn't anywhere near as loud as Guy's custom 4 pipe setup on his A8, which I've not experienced from inside the car so can't comment how noisy it is on a run compared to the Milltek.
It does give a nice deep V8 burble. Can try and get a video of it at the weekend, although there's probably one already on You Tube somewhere?
Offer stands anyway if you're down this way anytime - I'm generally about during the day
