Unlock the true sound of your Audi S4 or S5 B8/B8.5 with the Valvetronic Valved Sport Exhaust System. Designed specifically for the 3.0T supercharged V6, this system transforms the traditionally tame factory exhaust into a high-pitch, exotic, aggressive tone unlike anything else on the platform. At low RPM, the system produces a deep, throaty rumble, while higher in the rev range it unleashes an exhilarating F1-style scream—delivering a completely new auditory experience for Audi enthusiasts.

Constructed from premium T304 stainless steel, the exhaust system features 2.5-inch fully mandrel-bent piping for optimized flow and reduced restriction. A high-pitch X-pipe design creates a distinctive, exotic exhaust note while enhancing exhaust scavenging for improved efficiency. Precision TIG welding ensures high strength, durability, and long-lasting performance.

The vacuum-actuated valves allow instant control over the sound profile. With the included key fob remote, you can switch between aggressive, loud exhaust tones with the valves open, or a refined, quiet tone when the valves are closed—perfect for daily driving. The system is also 12.3 lbs lighter than stock, reducing rear-end weight and improving overall responsiveness.

Designed as a direct bolt-on upgrade, installation requires no cutting or permanent modifications and is fully reversible.
