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.
