Audi B9 S4 & S5 Valved Exhaust System
Full T304 Stainless Steel System with Electronic Valve Control
Overview
The Audi B9 S4 and S5, powered by the EA839 3.0L V6, have impressive performance potential—but the stock exhaust hides much of this engine’s true character. The Valvetronic Designs Full Valved Exhaust System unleashes its voice, delivering an aggressive, motorsport-inspired tone when desired, and stock-like refinement when needed.
Unlike typical setups requiring multiple components from different vendors, our system is engineered as a complete solution—from the OEM or aftermarket downpipe all the way to the exhaust tips. This single-package design eliminates the need for mixing and matching resonator sections or axle-backs from other brands, ensuring perfect fitment, seamless performance, and consistent sound quality.
With valves open, expect a bold exhaust note, pronounced overrun crackles, and a commanding presence. With valves closed, the car returns to quiet factory manners, with zero drone when paired with the OEM downpipe.
For those upgrading from the V8-powered B6 or B7 S4, our system delivers the level of engagement and emotional sound you’ve been missing—ensuring your B9 ownership experience is just as exciting.
