Audi RS4 RS5 B9 B9.5 2.9T Vortex Performance Exhaust System - Valvetronic V6 Sound

Audi RS4 & RS5 B9 B9.5 2.9T Vortex Performance Exhaust System - Valvetronic V6

The Perfect Sound for the Ultimate V6 Duo

The Audi RS4 Avant and RS5 are engineering marvels, blending daily utility with supercar-slaying performance. However, the factory exhaust often leaves the 2.9T Twin-Turbo engine sounding overly civilized. The Vortex Performance Exhaust System is specifically tuned to unlock a deep, aggressive, and exotic tone that matches the aggressive aesthetics of the B9 platform. Whether you're driving the ultimate "Super-Wagon" or the sleek Sportback/Coupé, this system provides the visceral V6 symphony you’ve been looking for.

Key Performance Highlights

• Dual-Mode Valvetronic System: Seamlessly integrates with Audi Drive Select. Keep it quiet and sophisticated in "Comfort" mode for daily errands, or switch to "Dynamic/RS" mode to open the high-flow valves for an unfiltered, high-decibel V6 roar.

• Anti-Rasp Resonance Tuning: Engineered with a precision X-pipe and center resonator to eliminate the high-pitched "rasp" often associated with V6 engines, replacing it with a deep, smooth, and authoritative growl.

• Performance-First Engineering: By reducing backpressure and optimizing exhaust scavenging, the Vortex system allows the twin-turbos to spool faster, yielding noticeable improvements in throttle response and mid-range torque.

• Lightweight & Durable: Available in premium T304 Stainless Steel or Grade 1 Titanium. Our system is engineered to be up to 40% lighter than the bulky OEM sport exhaust, improving handling and agility.
