Lamborghini Aventador SVJ / Ultimae – Valved Rear Section + Equal-Length Downpipes

High-Pitch V12 Character • Anodized Gold T304 Stainless • Vacuum Valve Control

Overview

The 6.5L V12 in the Aventador SVJ and Ultimae is nothing short of a masterpiece—but when paired with our Valvetronic Designs Valved Rear Section and Equal-Length Downpipes, it becomes a legend. This setup delivers a soaring, high-pitched tone reminiscent of the LP640 Murciélago, unlocking the character Lamborghini’s halo cars truly deserve. There is no compromise—only perfection.

Sound & Control

• Valves Open: A raw, F1-inspired wail that climbs to the 8,700 RPM redline with spine-tingling clarity.

• Valves Closed: Civilized, refined, and neighborhood-friendly for early mornings and long-distance cruising.

• Vacuum-Actuated Valves: OEM-style integration with the included controller for seamless mode switching.

Why Equal-Length Downpipes?

The factory exhaust features uneven runner lengths that flatten the tone. Our equal-length design harmonizes exhaust pulses, raising pitch and enhancing note clarity. The result is a sharper, cleaner, and more exotic sound signature—exactly what a V12 Lamborghini should deliver.

Construction & Craftsmanship

• Material: Premium T304 stainless steel with a stunning anodized gold finish for heat resistance and visual impact.
