Will Milltek S6 C6 downpipes fit a A6 C6 4.2?

Ive been searching around and trying to find if they can be made to fit. I saw on a forum that a guy had them on his S6 and said they were compatable with the A6 4.2 also. The pipes look like the same lines as my car. I have the chain driven 4.2 just like the S4 and S6.
