Adding S7 rear valence and quad tips
 

Since getting the Stasis tune and Injen intake, I decided to go all the way and install the beautiful S7 rear valence so I can complete the quad exhaust look like I did on my A5. This may come in handy if you want to add the full quad S7 exhaust from AWE to your A7. Some may recall my December post: Poor man's way to an Audi A7 quad exhaust.

The A7 mufflers already have the extra opening (sealed stubs) for the quad tips. Go ahead, get under your A6/A7 rear end and take a look for yourself.

I removed the A7 valence with a thin screwdriver (3 screws and many snap tabs) and the S7 one just snaps into the same slots. I have the additional two Audi tips on order and will have them welded on next week to replace the downward facing, formerly hidden extra spouts.

Cost so far is a bit over $500. Part #'s for the S7 valence and strip are:
4G8-807-521-B-1RR
4G8-807-791--3Q7
Tips are another $200 and I expect additional labor to be $250 for welding. If anyone wants to buy the old A7 valence, let me know.

It took about twenty minutes and I broke a few tabs before figuring out the system. Once I had the new valence, I could see exactly where the click tabs were so I just decided to go for it. The tabs are about 3 3/4" apart(see photo below with the white circles). The first one on the end is tricky but you can see how it works and it soon releases when you press correctly. The rest are best done with a thin, flat head screwdriver or a narrow but strong putty knife. A radio or moulding install tool is likely the best but I do not own one. Amazon sells this it for about $10. You just line up the tool at the right spot on the tab, slide in and lift up a bit when in. The valence releases a few inches at a time. I got pretty good at it in the end. The blue circles show one of the three screw tabs that attach under the gas tank.
Last photo is of the new valence installed but with the hidden exhaust suddenly exposed.

(It now feels like my zipper is open until I get the other tips put on.)

I wanted to do this to my A7...nice work man

adding S7 rear valence
 

I wanted to install the S7 rear valence on my A7 but dind't knew until now if the S7 rear valence would fit the A7 rear bumper.When I read you everythings seems OK,but there is still a question for me not anwsered: In europe Audi offer two kind of bumpers,Standard ones and "Sline"ones at extra cost which look a little more "sporty".I would like to know if your bumpers are of the Sline kind (as mine), if you have a way to know it,before to order parts My A7 has been up graded with an Abt box (410hp)so it deserve this kind of rear end!
Any way thank you for your thread,pictures,very clear.I'm inpatient to read the end of the story

My 2012 A7 is the standard and only USA version imported to the USA and the S7 valence numbers I gave above fit that bumper perfectly. Check out the USA rear photos on the web and compare to the S-Line in Europe. Audiusa.com

I agree that an ABT tune deserves a sexy quad exhaust and the S7 valence is a better look. I plan to post pictures when I am done.

As far as I can see U.S.specifications Audi A7 seems to have S line bumpers;that's good for me!Next step will be to cut the sealed stubs and weld
on it same tips as the ones already there.If you get their parts number I'll appreciate to known them.Any way I will start this job only once yours will be done and report
Thanks

Best of luck.

Many thanks for the information and precious parts diagram.

The Audi parts dept. made a mistake and now says that the OEM tips are $218 each. Ouch! I told them to forget it and instead got four tips from AWE and will have them welded on tomorrow.

At NateDog's metal shop in Hatfield, PA. (215) 361-1134. He does good work.

A7 is on the rack and just circumcised. Both long and short path openings on the stock Audi mufflers opened to 2 1/4" and ready for the AWE smoked black tips to be bolted on to the new pipes Nate will weld to the openings.

On the other side, the new AWE tips are tacked into place.

Last, view from the bottom & ready for the final welding. Note that both straight pipes are flared at each end and the AWE tips have a nice adjustment feature with the bolt on hardware.

That looks great! I'm looking forward to doing this on mine as well. Would be great if you could post up a few pictures when it's complete. :)

Looking very good so far.
Any change in sounds?
Can you upload a vid with sounds?

Here is the final product. I will try to get a video uploaded on Youtube soon so we can all make a comparison pre Stasis version.

My 2013 A7 w/20" Sport Package has a honeycomb rear valence.

I'm not sure, but maybe it's the angle of the photo take, but does the tips look a bit odd as compared to the S7? They look way too extended out. Can you try a picture from another angle?

One more from the rear view. Yes they are a bit more out than the stock A7 ones but that is how I wanted them. Why hide when the AWE tips are AWEsome.

While getting the tips done, I noticed that Ross-Tech was in Lansdale, PA and only 10 minutes away. I drove over and they did me a big favor and enabled a few VAG-COM codes: engine start dials sweep, gear indicator and remote window open. Great guys there.

Not too much change but don't forget, I already had the quad outputs (one was hidden & pointing down). It got louder when I opened up that short path, downward stub vs. stock exhaust. I guess having the short-path outlet pointing straight back should be louder as you watch me disappear into the horizon. :^)

Looks really good, nice one :)

Thanks. By the way, Revo and Stasis merged last year so the Stasis A7 ECU tune is available in Europe now, as I understand it.

Video of Results - Not the fastest launch but will do
 

Looks great!!:cool:

Did you just use the launch control there? :eek:

Apparently I did! (My left foot on the brake) I have had much better runs. I bet my 0-60 MPH time was about 5 seconds on that run. The sound is just not the same on a V8 however.

?? Does A7 has launch control??:confused: Do you mean by torque braking?

I believe the A7s with Stronic transmissions can be launched. There's a set of steps to do this. Just search this forums.

No stronic is US spec cars only tiptronic.

How are you liking the Stasis tune? Any issues? Would you do it again or a different route?

Love the Stasis tune
 

The car behaves like a very high powered beast at any speed.

Did the AWE Quad modification onto my A7 last week.

Used a carbon wrapped (S7) valance.

Audi A7 S-Line (UK) with AWE Quads on a carbon wrapped valance. Sounds S W E E T :)

Hey Jerry, sorry to bring back an older thread. I am getting ready to do a similar modification to my A7. I am getting conflicting part numbers from my local Audi dealer for the rear valance and strip.

I guess it may be possible these part numbers have changed since you did this? Let me know if these are the right parts according to the diagram if you can.

I'm getting:
4G88074341RR
4G88074219B9

#7, and #8 on the diagram: http://genuineaudiparts.com/parts/20...agramCallOut=8

The parts that I got per the invoice were:
4G8807 521B 1RR spoiler
4G8807 791 3Q7 strip

Good luck.

I am thinking about doing this mod as well on my 2014 A7, Premium plus trim. In my searching I keep seeing that you need the Prestige or S line trim / bumper to do this mod. In all of the photos of these mods, the bumper looks exactly the same as my bumper. Is there something different between the Prestige/S line and Premium bumpers that we cant see? Thanks

Prestige and sport have the gray lower valence with mesh. I'm not familiar with all years, but I believe that it only comes with Sport or Pretige which have the S-Line trim.

I have a Sport but not S-line trim. Probably the parts all bolt up but the colors are the issue in the part numbers. Then you have the S-line gray part number, then the S7 part number for 4 tips and then the RS7 part number with 2 tips again.

Got the part numbers sorted. Thanks ECS tuning!
