Valvetronic Designs Audi B9 S4 / S5 Valved System

Description

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 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.
