Carbon Rear Diffuser

[Welterweight]

On the hunt for a great looking higher quality diffuser for my 2014 Black S6. I found the Deval one but it’s a bit pricey. Any other good options? Any first hand experience is greatly appreciated. Thanks!

Xenoz.uk has good stuff but shipping will cost and it seems they're running out of stock. I've been looking for them too and it's not easy to find anything.

I personally wish someone would make a replica of the OEM C7.5 S6/S7 diffusor for the pre-facelift cars. Have not heard of anyone being able to retro-fit it.

Not unless you want to replace the whole bumper to do it.

I would love to swap out the rear tails for the C7.5 too...

Something I just learned from ordering the rs7 diffuser from XUK, they don't provide the framing that goes inside the diffuser to mount the oval exhaust tips. It's an additional 200 from Audi.

EDIT: This is only true if you have genuine Audi exhaust tips. XUK can provide tips that are glued in.
Since I had genuine Audi exhaust tips, I needed this part: https://parts.audiusa.com/p/Audi__RS...G8807319A.html

There's a thread for that, it's not that difficult.

Damn that's bogus, I was considering getting that diffuser too.

I wouldn't let that stop you, but it is a minor inconvenience that's costing me another day without my baby after 2.5 months without it. Lol

Ya I'm going to have to let her go for close to a well next month doing upgrades and maintenance. Then I'll get into the asthetics if it.

So it turns out I was wrong. I talked to the guy at XUK and found out that if I would have bought their exhaust tips, they would have been specially made to glue into the diffuser.
I didn't buy their exhaust tips tho because I already had genuine audi black optic exhaust tips.

Ah that makes more sense, looking at their website it looked like the tips attached to the diffuser.

On the website it says fits A6 non S line. Is that what you drive?

deval or carbon designz are pretty much the options. maybe you can get lucky and find one used. i did but it still cost me $750...

How is the fit and finish? If it’s really sexy I will jump!

The Deval rear diffuser is a flush fit and looks a lot better than the stock diffuser. Highly recommend.

From what I can find Deval doesn't have one for the A7 only the other sub models.

Agreed. Deval looks fantastic. There aren't many options.
