Let me first say, this was a lot more work than I expected it to be.

Part Number: 8EC 071 611A 9AX
Cost: ~$250
Paint: ~$90

First you remove the old exhaust cutout. This is done by removing two screws underneath the bumper. Next the two rivets on the sides must be drilled out. Fortunately Audi forgot to install mine, so I skipped that step.

The old cover removed:

Next you must cut the lip down. I used a jig saw. Be VERY careful not to hit the metal crossbeam behind the bumper skin. It caused my jigsaw to skip out and ding my bumper paint (even through 5 layers of duct tape).

Lip cut in half:

The instructions call for removing the riveted support pieces underneath. I skipped this step and used the spacers provided to create a buffer between the bumper skin and metal bar. I had a lot of trouble pushing the clips into the bumper because it's so flexible. The plastic spacers kept everything still. I attatched string to them and when I was done, pulled them out.

All in all, I think it looks much better than the factory flat black piece!

I'll probably let the body shop do the install though.

I agree that it looks so much better than the flat black plastic diffusor that comes from the factory.

Speaking of flat black plastic -- I am thinking about leaving off the black plastic trim piece that screws into the back side of the diffusor, or maybe replacing it with some sort of grille material. What do you think? Does that piece serve any functional purpose?

and price wise seemed reasonable (for paint)! Im not sure I would be comfortable putting a jig saw to mine by myself yet tho! Id need help!
Are you planning on the trunk-spoiler at all?

I also agree- yours it one of if not the best so far! A perfect roll-model for MODs done well! heh

Can I have a print-out of how to remove the stock exhaust diffuser? I see your pics but any pics of how to take it off? As in from underneath the car? Thanks! Mikey

nope, no plans for the spoiler, I think it's too busy.
