VRP Audi S4 B9 Titanium Valvetronic Exhaust System
Precision-engineered for the 2017–2022 Audi S4 (B9 chassis), the VRP Titanium Valvetronic Exhaust System transforms your sedan into an auditory masterpiece. Designed to balance refinement and aggression, this system embodies the perfect fusion of lightweight materials, meticulous craftsmanship, and intelligent sound control — a tribute to both German engineering and performance artistry.
Constructed entirely from aerospace-grade titanium, the VRP system delivers a dramatic reduction in weight — nearly 50% lighter than the factory exhaust. This isn’t just about numbers; it’s about balance, response, and control. Reduced unsprung mass translates to sharper turn-in and quicker acceleration, amplifying the responsiveness that defines the S4’s Quattro DNA.
The system’s 3.0-inch mandrel-bent piping ensures unobstructed flow from the turbocharged 3.0T powerplant, producing immediate throttle response and improved mid-range power. At the rear, twin muffler canisters transition into quad carbon-fiber tipped outlets, each precision-aligned within the factory valance for a flawless visual finish.
The true magic lies within the Valvetronic control module. With the press of a button, the exhaust’s internal valves open or close to adapt instantly to your mood or driving environment.
Valves Closed: A refined, deep-toned character ideal for daily driving and long commutes — smooth, composed, and sophisticated.
Valves Open: A raw, exhilarating symphony that channels the S4’s full turbocharged energy into an unmistakable titanium resonance.
Every weld, hanger, and flange is CAD-modeled and 3D-scanned to align with factory mounting points — ensuring perfect fitment without cutting or modification. The system integrates seamlessly with OEM heat shielding, mid-section brackets, and stock rear diffuser geometry, making it a true bolt-on upgrade.
Beyond its acoustic brilliance, the titanium construction gives the system a unique bluish-gold heat patina over time — an aesthetic hallmark of authentic titanium craftsmanship. The carbon-fiber exhaust tips complete the look, giving the rear of your S4 a commanding yet elegant presence.
With every rev, the VRP Titanium Valvetronic Exhaust System redefines what it means to drive an Audi S4. It’s not just an exhaust — it’s an instrument. A precision-tuned, lightweight, and intelligent system built for those who demand control, sound, and soul in equal measure.
- Precision fitment thanks to 3D scanning and CAD modeling
- 3-inch (76mm) diameter mandrel-bent tubing throughout
