2016-2018 For Audi A6 S6 C7.5 Rear Diffuser With Tailpipe Exhaust Tips

Product Description

Overview

Transform the rear profile of your 2016–2018 Audi A6/S6 C7.5 with this RS6/S6 style rear diffuser. Designed specifically for the facelifted C7.5 platform (2016–2018), this diffuser replaces your factory rear valance with the aggressive, high‑performance look of the RS6/S6—featuring a gloss black UV‑stabilized ABS construction, an aggressive sculpted design, and tailpipe exhaust tips.

The rear diffuser is one of those parts of the car that most people do not even notice, but it plays a large role in the vehicle’s aerodynamic stability and overall aesthetic. This RS6‑inspired diffuser not only gives your A6/S6 a menacing wide‑stance look but also actively reduces drag and improves rear‑end stability at higher speeds.

5 Key Features

1. Aggressive RS6/S6 Style Design
Give your A6/S6 C7.5 the sharp, race‑bred look of the RS6/S6. The sculpted fins and quad‑exhaust‑tip layout create a bold, motorsport‑inspired appearance that dramatically enhances the rear profile. This design was engineered and designed in‑house to add a more aggressive appearance to the rear of your vehicle while matching the factory appeal of your Audi. The exclusive design adds a deep high‑gloss shine and provides an aggressive and sporty style that’s sure to set your vehicle apart from the rest.

2. Complete Kit with Tailpipe Exhaust Tips
All‑in‑one conversion kit includes the rear diffuser and exhaust tips. Everything you need for a complete RS6 style rear transformation – no separate purchases required. The diffuser features a dual‑tip/dual‑outlet design that fits factory and most aftermarket exhaust systems and accepts exhaust tips up to 4″ in diameter. We provide a pair of stainless‑steel exhaust tips with a black‑chrome finish and a pair of brackets.

3. Premium Gloss Black ABS Construction – UV Stabilized
Manufactured from high‑quality UV‑stabilized ABS polymer—the same material used in OEM bumpers and body parts. The deep high‑gloss black finish is UV‑protected to prevent fading, yellowing, or bubbling from harsh sunlight, ensuring your diffuser looks showroom‑fresh for years. No painting required – ready to install out of the box. Optionally, a premium pre‑preg dry carbon fiber (60% lighter than standard layups) version is available for those seeking the ultimate in weight savings and weave aesthetics.

4. Direct Fitment for C7.5 (2016–2018) – No Cutting Required
Engineered for a perfect OEM+ fit onto S‑Line or S6 rear bumpers only. This diffuser fits your vehicle using the factory mounting locations and hardware. Installs with no drilling, cutting, or modification of any kind required. Simply remove your currently installed valance, line up all tabs, and lightly press the diffuser in place until the tabs click into position.

5. TUV MATERIALGUTACHTEN & CE Certified
This product has received TUV MATERIALGUTACHTEN certification, verifying material quality and safety for road use. It is also CE certified and EPR (France/Germany) compliant, meeting rigorous European safety, quality, and environmental regulations. The product arrives with a protective film vacuum‑sealed to it – do not remove the protective film until you are certain the product fits, as removal will void any returns (e.g., due to accidental damage during test‑fits). If you decide to paint the diffuser, primer must be used first.

Frequently Asked Questions

Q1: Will this fit my 2016–2018 Audi A6 or S6?

A: Yes, if your vehicle is a C7.5 facelift (2016–2018) with an S‑Line or S6 rear bumper. This diffuser will NOT fit standard (non‑S‑Line) A6 bumpers. Contact us with your VIN for confirmation.

Q2: How do I know if my A6 has S‑Line or Non‑S‑Line?

A: The S‑Line exterior package includes sportier bumpers, side skirts, and fender badges. If your A6 does not have these, you have the standard (Non‑S‑Line) bumper. S‑Line and RS6 rear diffusers are physically incompatible with the standard A6 bumper.

Q3: Does this kit include exhaust tips?

A: Yes! The complete kit includes a pair of tailpipe exhaust tips, bracket kit, self‑tapping screws, and 3M VP Tape – everything you need for a full RS6/S6 style rear transformation.

Q4: Does the diffuser require painting?

A: No. It comes in a premium high‑gloss black UV‑stabilized finish – ready to install out of the box. UV‑protection prevents fading and yellowing. However, if you decide to paint the diffuser, primer must be used first.

Q5: Is drilling required for installation?

A: No. The diffuser installs with no drilling, cutting, or modification. You replace the current valance using factory mounting locations and tabs.

Q6: Is professional installation required?

A: Yes. Professional install of this diffuser by someone with aftermarket product experience is strongly recommended. Rear bumper removal may be required, and self‑tapping screws could be needed in corners/tabs for the best fit.
