Audi B9 S4 / S5 3.0T Valved Sport Exhaust System | Vortex

Elevate Your B9: The Definitive V6 Sound Experience

The Audi B9 S4 and S5 are engineering marvels powered by the potent 3.0T V6 EA839 engine, but the restrictive factory exhaust leaves its true acoustic potential muted. The Vortex Valved Sport Exhaust System is precision-engineered to unrestrict your vehicle, delivering a significant boost in exhaust velocity, sharpened throttle response, and a captivating, aggressive V6 growl that transforms your daily drive.

Intelligent Sound Control: Dual Personalities

Experience the best of both worlds with our integrated valvetronic technology. Retain total command of your exhaust note—keep the valves closed for a refined, drone-free cabin during highway cruising or early morning cold starts. When it’s time to perform, open the valves to unleash the raw, unfiltered Vortex roar on the open road.

Uncompromising Craftsmanship: Choose Your Material

We craft performance without compromise. Choose the material that perfectly aligns with your build philosophy:

• Aerospace-Grade Titanium: The ultimate track-focused upgrade. Drastically reduces overall weight at the rear axle for improved handling dynamics while delivering a distinctively sharp, exotic, and high-frequency resonance.

• Premium T304 Stainless Steel: The industry standard for extreme durability. Offers exceptional corrosion resistance and a deep, powerful rumble that commands attention.

Key Performance Features

• Optimized Flow Dynamics: Mandrel-bent piping ensures smooth, unrestricted exhaust gas flow, reducing backpressure and maximizing turbo efficiency.

• Direct Bolt-On Installation: 3D-scanned and engineered specifically for the B9 chassis, ensuring a perfect, seamless fitment without the need for cutting or welding. (Professional installation recommended).
