2019-2025 For Audi A6 S6 C8 C8.5 Rear Diffuser With Tailpipe Exhaust Tips

Product Description

Overview

Transform the rear profile of your 2019–2025 Audi A6 or S6 C8/C8.5 with this RS6/S6 style rear diffuser. Designed specifically for the C8 and C8.5 platforms (2019–2025), this diffuser replaces your factory rear valance with the aggressive, high-performance look of the RS6/S6—featuring a gloss black finish, sculpted aerodynamic fins, and tailpipe exhaust tips.

The C8/C8.5 generation brought sharp, modern styling to the A6/S6 lineup. This RS6-inspired rear diffuser builds on that foundation, offering a sportier, more commanding presence from every angle while enhancing rear-end aerodynamics. Additionally, this diffuser features functional exhaust tips that can be connected to your existing exhaust system for genuine performance sound.

Complete Conversion Kit: Includes rear diffuser, tailpipe exhaust tips, self-tapping screws, 3M VHB tape, and installation manual.

Aerodynamic Benefits: The sculpted fin design channels airflow, reduces drag, and enhances rear-end stability at higher speeds. This diffuser works by smoothing the airflow exiting from underneath the vehicle, reducing turbulence and lowering aerodynamic drag.

5 Key Features

1. Aggressive RS6/S6 Style Design
Give your A6/S6 C8/C8.5 the sharp, race-bred look of the RS6/S6. The sculpted fins and extended lines create a bold, motorsport-inspired appearance that dramatically enhances the rear of your vehicle. The design incorporates rounded exhaust tip surrounds that echo the styling of Audi's RS models.

2. Complete Kit with Tailpipe Exhaust Tips
All‑in‑one conversion kit includes the rear diffuser and tailpipe exhaust tips. Everything you need for a complete RS6/S6 style rear transformation – no separate purchases required. The functional exhaust tips can be integrated directly with your existing exhaust system for genuine performance sound and improved exhaust gas flow.

3. Premium Gloss Black ABS Construction
Manufactured from high‑quality ABS plastic – the same material used in OEM bumpers and body parts. ABS plastic was specifically developed for use in the automotive industry and is used for the production of bumpers and other body parts. It offers excellent resistance to impacts, scratches, moisture, and extreme temperature fluctuations, ensuring longevity and sustained visual appeal even under demanding conditions. The high-gloss black finish is UV‑protected to prevent fading and yellowing and matches factory gloss black trim perfectly.

4. Direct Fitment for C8/C8.5 (2019–2025) – S-Line/S6 ONLY
Engineered using 3D scanning technology for a perfect OEM+ fit. Designed exclusively for Audi A6 S-Line and S6 C8/C8.5 bumpers. Replaces the factory OEM rear diffuser and uses factory mounting points with self-tapping screws and 3M tape for a secure, rattle-free installation. To get better results from the installation, we recommend taking the rear bumper off the vehicle.

This product has received TUV MATERIALGUTACHTEN certification, verifying material quality and safety for road use. This certification signifies that the product has undergone rigorous testing and meets stringent European safety and quality standards. It provides assurance regarding fitment, material integrity, and road legality. Each diffuser features a protective film and UV-repelling coating for long-term durability.
