Ferrari F12 / F12 TDF / 812 (GTS) Titanium Valved Exhaust
Special Ops Series • Vacuum Valves • Refined Tone, Minimal Drone
Overview
The 6.3-liter Ferrari V12 proves why naturally aspirated is king. While the F12/812 sounds fantastic from the factory, many “bypass” solutions simply chase volume. Valvetronic Designs Special Ops takes a different path: our titanium valved rear muffler bypass is tuned for pitch and quality—a modest increase in volume with valves open, and a composed, drone-minimized demeanor with valves closed.
Originally engineered for an owner who wanted a more musical, better-balanced exhaust (not just louder), this system now joins our Special Ops program for discerning V12 enthusiasts.
Sound & Control
-
Valves Open: Raw, unfiltered V12 timbre with a higher, cleaner pitch—think more song, not just more sound.
-
Valves Closed: Reduced volume and minimized cabin drone for relaxed cruising.
-
Vacuum Valve Integration: Operate via standalone controller or tie into the OEM valve solenoid for factory-style behavior.
Design Priorities
-
Pitch Over Pure Volume: Tuned to elevate the F12/812’s natural harmonics
-
Bypass Architecture: Replaces rear mufflers to reduce restriction and unveil the engine’s character.
-
Daily Usability: Civil when closed, F1 inspired scream when open.
Construction & Craftsmanship
-
Material: Ti-6Al-4V Grade 5 titanium—ultra-light, heat-resistant, and corrosion-proof.
-
Weight Savings: –25.8 lb versus factory rear sections.
-

-
Reversible: 100% bolt-on; return to stock at any time.
