Audi C8 RS6 Avant & RS7 Sportback Valved Cat-Back Exhaust System

Full Titanium System with Electronic Valve Control & Integrated H-Pipe

Overview

The C8 RS6/RS7 pairs long-distance comfort with serious pace—but the factory exhaust keeps the 4.0L twin-turbo V8 far too quiet. The Valvetronic Designs Titanium Valved Cat-Back transforms the experience, delivering a raw, motorsport-inspired soundtrack with the valves open, and a refined, grand-touring tone with the valves closed.

Crafted entirely from titanium and engineered around a large cross-section H-pipe, this system improves exhaust scavenging and throttle response while staying drone-free in either mode. For maximum presence and performance, pair it with our free-flow front bypass pipes.

Note: Valve simulators are recommended on this platform to prevent CELs related to factory valve monitoring. Contact our support team for guidance.

Why It Works

• Titanium Construction: Significant weight reduction and rapid heat dissipation for sharper response.

• Large Cross-Section X-Pipe: Enhances scavenging for a cleaner, more exotic tone.

• Full-System Tuning: Designed as a cohesive cat-back for consistent sound quality and fitment.

Sound & Control

• Valves Open: Full-bodied V8 aggression, pronounced midrange, and a sharper top-end note.

• Valves Closed: Subtle, composed tone ideal for daily use and highway cruising.

• Bypass Pipes (Optional): Unlock maximum volume and presence when combined with the cat-back.
