I think I will be going with the AWE.

I think you need to be careful selecting which exhaust - or at least which exhaust tip your going to use. An AWE Quad with standard tips is not going to fit that rear diffuser.

Talk to your exhaust dealer and explain you have the RS7 diffuser fitted, he may be able to either swap the tips to something that fits, or delete the tips completely saving you some $.

On the RS7 model, the actual exhaust tips do not extend through the diffuser opening. If you try and fit a quad with regular tips, you will find the spacing of the tips too wide to fit through that oval.

+1 I wouldn't buy the quad tip. No way it will fit. However talk to AWE. I am rather certain they made a dual tip A7 exhaust to fit the factory rear. So you might still be able to get AWE but will need to modify. There are a couple guys on this site and AZ that have done extensive RS conversions on C7 cars. One guy is from Romania I think. Has a red A6. Another guy is stateside and has an S6. Both are beautiful jobs and they will return a PM.
