Audi C7 RS6 & RS7 Valved Cat-Back Exhaust System

Grade 5 Titanium with Integrated X-Pipe

Overview

The Audi RS6 and RS7 C7 platform strikes a rare balance between comfort and blistering performance—making it one of the most capable grand tourers on the road. But while the 4.0L twin-turbo V8 delivers incredible power, its factory exhaust leaves much to be desired.

The Valvetronic Designs Valved Cat-Back Exhaust System transforms the RS6/RS7 into a true auditory experience. Constructed from the highest-quality Grade 5 Titanium, this system delivers an aggressive, motorsport-inspired tone with the valves open, and a refined, drone-free soundtrack with the valves closed.

For those seeking the ultimate sound, pairing the system with our free-flow front bypass pipes unlocks maximum volume and performance—while the large cross-section X-pipe improves exhaust scavenging for unmatched tone and response.
