Mandatory Link Pipe Set for the Akrapovic RS6 and RS7 C8 Evolution Line System
The Akrapovic L-AU/SS/6 Link Pipe Set is the required companion component to the Akrapovic Evolution Line (Titanium) exhaust for the 2020+ Audi RS6 Avant C8 and RS7 Sportback C8 4.0L V8 twin-turbo platform. Because of packaging requirements, the L-AU/SS/6 ships separately from the muffler section (S-AU/TI/15H / S-AU/T/2H) and must be ordered alongside it for a complete cat-back system. Constructed from T304 stainless steel with TIG-welded seams and precision-flanged ends, L-AU/SS/6 reduces exhaust back-pressure in the C8 mid-section, contributes to improved throttle response, and brings the full Akrapovic sound signature to the RS6 and RS7's 4.0 TFSI. Note: this part does not fit with the DP/L-AU/SS/1 downpipe configuration.
Key Features
- T304 Stainless Steel Construction – Mandrel-bent and TIG-welded stainless steel resists corrosion and high thermal cycling for long service life
- Required for Complete Evolution Line System – L-AU/SS/6 is a mandatory companion part to Akrapovic S-AU/TI/15H and S-AU/T/2H for the RS6/RS7 C8 platform
- 1.30 kg Total Weight – Lightweight stainless construction reduces exhaust system mass versus factory mid-pipe components
- Direct Bolt-On Fitment – Precision-flanged ends match the RS6 / RS7 C8 factory exhaust mount locations without modification
- Dual Model Compatibility – Fits both 2020+ Audi RS6 Avant C8 and RS7 Sportback C8 with the same part number
- Non-CARB Compliant – Verify local emissions regulations before purchase; not approved for California on-road use
- Handcrafted in Slovenia – Produced at Akrapovic headquarters to motorsport quality tolerances

Frequently Asked Questions
Is the L-AU/SS/6 a complete exhaust system or just part of one?The L-AU/SS/6 is a link pipe set, not a complete system. It is a mandatory companion part to the Akrapovic Evolution Line muffler (S-AU/TI/15H or S-AU/T/2H) for the RS6/RS7 C8. Both must be ordered together for a complete cat-back system.
Does the L-AU/SS/6 fit the DP/L-AU/SS/1 downpipe configuration?No. The product title explicitly states that L-AU/SS/6 does not fit when the DP/L-AU/SS/1 downpipe is installed. Verify your exhaust configuration before ordering.
Does L-AU/SS/6 fit both the RS6 Avant and RS7 Sportback on the C8 platform?Yes. The Akrapovic L-AU/SS/6 fits both the 2020+ Audi RS6 Avant (C8) and RS7 Sportback (C8) 4.0L V8 twin-turbo models with the same part number.
Is the L-AU/SS/6 CARB compliant or street legal in California?No. The L-AU/SS/6 is not CARB compliant and is intended for competition or off-road use. It is the buyer's responsibility to verify local emissions regulations before purchasing and installing.
Why does the L-AU/SS/6 ship separately from the muffler section?Akrapovic ships the L-AU/SS/6 link pipe set under a separate part number because of packaging requirements. Both the link pipe set (L-AU/SS/6) and the muffler section (S-AU/TI/15H or S-AU/T/2H) must be ordered to complete the full cat-back system for the RS6/RS7 C8.
What material is the L-AU/SS/6 made from?The Akrapovic L-AU/SS/6 is constructed from T304 stainless steel with TIG-welded seams and mandrel-bent pipes to ensure smooth internal flow and long-term corrosion resistance.
How much does the L-AU/SS/6 weigh?The complete L-AU/SS/6 link pipe set weighs 1.30 kg, which is lighter than the factory mid-section it replaces.
Does Akrapovic warranty the L-AU/SS/6?Yes. Akrapovic covers the L-AU/SS/6 with a 2-year warranty against manufacturing defects when purchased through an authorized dealer.
Installation Instructions
