Valvetronic Designs AUD.B9.S4.VSES.BR.BRSH: A Symphony of Engineering and Performance

The Audi B9 S4 and S5, powered by the formidable EA839 3.0L V6 engine, possess an inherent performance potential that remains largely untapped with the factory exhaust system. Enter the Valvetronic Designs Full Valved Exhaust System, a meticulously engineered solution that transforms your driving experience by revealing the true character of this remarkable powerplant. This exhaust system is not merely an enhancement; it is a reimagining of your vehicle's auditory identity, delivering a motorsport-inspired soundscape when desired, and a refined, stock-like demeanor when the situation calls for discretion.

Design & Engineering

Unlike conventional aftermarket solutions that cobble together disparate components, the Valvetronic system is conceived as an integrated package, engineered for seamless compatibility from the OEM or aftermarket downpipe to the elegantly styled exhaust tips. This holistic approach ensures perfect fitment and flawless performance, eliminating the pitfalls of mismatched components that plague lesser systems.

When the exhaust valves are engaged, the system produces a bold, aggressive exhaust note characterized by pronounced overrun crackles and a commanding presence that resonates with enthusiasts. Conversely, with the valves closed, the system reverts to a refined, quiet operation, maintaining the factory's tranquility without the intrusion of drone, especially when paired with the OEM downpipe. This duality not only enhances the driving experience but also preserves the vehicle's versatility—ideal for both spirited drives and everyday commutes.
