For drivers who demand a lightweight, exotic-sounding system that doesn’t compromise daily usability, VF Engineering’s Titanium Valved Exhaust Systems are the answer. Each system is crafted from aerospace-grade titanium for significant weight savings and delivers a deep, aggressive tone that transforms the character of the vehicle it’s built for. Available now through Bulletproof Automotive, these valved catback systems cover top-tier applications, including the Porsche 911 Turbo S (992.1), Audi R8 4S, Lamborghini Aventador SVJ/Ultimae, and the Huracan STO, Tecnica, and Sterrato. This is performance redefined with precision, power, and purpose.
Built to OEM standards for the 2019–2024 Porsche 911 Turbo and Turbo S (992.1), VF Engineering’s titanium valved catback exhaust sheds 15.4 pounds over the factory system. It pairs race-grade titanium construction with a valved layout that allows the driver to toggle between refined and raw.
In daily mode, the system is composed and subtle. Switch to Sport or Sport Plus, and it delivers a sharper, deeper growl that brings out the best of the 3.7L twin-turbo flat-six. No software is required, but tuning is recommended to unlock its full potential. The system retains factory tips and includes O2 spacers for ease of installation. It’s the perfect upgrade for enthusiasts who want more sound, better throttle response, and true weight reduction.
For 2020–present Audi R8 4S models, this valved exhaust saves a massive 53 pounds over stock. The 5.2L V10 becomes a different animal with the valves open, producing a high-pitched, motorsport-inspired note with zero rasp or drone. With the valves closed, it’s well-behaved enough for neighborhood cruising or long drives.
Each unit is crafted from high-grade titanium and engineered to use the OEM tips and valve actuators. The result is a plug-and-play solution that doesn’t trigger warning lights or require modification. While software isn’t required, it’s recommended for optimal horsepower and torque gains. For R8 owners who want the sound this car should’ve had from the factory, this is it.
Tailored for the LP770-4 SVJ and LP780-4 Ultimae Aventador models, this system is the final touch for Lamborghini’s most extreme V12s. The titanium construction drops 53 pounds of weight off the rear end, helping improve weight distribution and power-to-weight balance.
With valves open, the V12’s howl becomes race-car sharp and emotionally addictive. Closed, it delivers a reserved but purposeful tone. Compatible with both coupe and roadster variants, the system uses factory tips and does not require any cutting or tuning to install. Still, as with all VF units, a tune is suggested for peak results. If you drive an SVJ or Ultimae, this exhaust matches the exclusivity and performance your car already commands.
This system covers the LP610-4 and LP640-2 Huracan platforms, including the Sterrato (2023–2024), STO (2021–2024), and Tecnica (2022–2024). Titanium construction slashes 28.7 pounds off the car’s rear and unlocks the true soundtrack of Lamborghini’s 5.2L V10.
While tips are not included in this system, it’s fully valved and integrates seamlessly with OEM electronics. Closed valves keep the car tame for street or highway use, but with the valves open, the tone becomes sharp, screaming, and unmistakably exotic. The Huracan was already a standout; this system gives it the edge it deserves.
Titanium isn’t just useful for being lightweight; it’s about tone, heat resistance, and longevity. VF Engineering chose it not just for the numbers on a scale but for the way it shapes sound. Titanium resonates differently than stainless steel or Inconel, creating a crisp, raw tone that amplifies the best qualities of each engine. It also resists corrosion and thermal breakdown better than traditional materials. Whether it’s the howling V10 of an Audi or the snarling Flat 6 of a Turbo S, this material delivers a clean, captivating exhaust note without compromise.
