Hey guys, I have a 2016 A7 in the prestige + black optics trim package. Is it possible to replace the stock black rear diffuser for a S7 or RS7 carbon fiber diffuser on that bumper? Or do I need to go aftermarket. I'd like to stay OEM if possible unless y'all suggest otherwise.

Any opinions?

Because you have the Prestige variant of the A7, by default you have the 'S-Line' package, that means if you obtain the S7 or the RS7 lower rear diffuser it'll fit just fine on your bumper (after removing your piece naturally).

Personally I went aftermarket but to each their own.

Will the awe diffuser have fitment problems?

AWE is a known brand, history of quality, I say the chances are very high that it'll fit just fine; you may need to take your time and line things up and possible that some adjustments may be needed.

I also don't want you to over think it, if you remove your factory insert piece (take your time) you'll see its pretty simply by design and flexible so the AWE piece shouldn't be an issue.

You probably need to do some homework, if you did you'd know the RS diffuser will not fit the S7 nor A7 S line.

My car had the RS7 rear diffuser, removed it because I wanted to go quad exhaust (and sold it), so my 'homework' was based because I had the part on my A7 S-Line bumper...

Normally I would leave it at that, but its very possible that my RS7 carbon fiber diffuser that was on my car (3rd owner) was aftermarket, so I'll throw some doubt out there.
