I want to place an 02' A6 rear bumper w/ valence on my 01' A6 C5. The reason being that I want to add a new exhaust system with tips on my 01', so I wouldn't have to cutout anything. I want to replace my 01' bumper anyway due to the chips and dings.

 

I saw your post and wanted to touch base with you to see if you had any luck, or to see what you ended up doing. Let me know, because I am going through the exact same thing. I have a 2000 A6 4.2 that I want to upgrade the exhaust on, and not have to start cutting away on my car. Let me know how it goes, I'm interested to see what you came up with.

 

Any update on this? I want to do the same thing and want to know if this is possible
