Voltage Exhaust System for LP770-4 / LP780-4 Lamborghini Aventador SVJ and Ultimae

Built specifically for the Aventador SVJ and Ultimae, the Voltage Exhaust System gives you two distinct personalities on demand. Valves closed keeps things hushed and refined; valves open opens things up for a free-breathing, assertive tone. Hand-built in your choice of T304 Stainless Steel, which offers long-term durability and a fuller timbre, or aerospace-grade Inconel for lighter, thin-wall construction and a crisper note. Back-purged TIG welds, smooth mandrel bends, and tight-tolerance flanges come together for a rigid, leak-free assembly. The straight-through path in open mode cuts restriction for sharper throttle response, while high-temperature brackets and hardware keep everything stable through repeated heat cycles. This is a precise, vehicle-specific replacement for the rear section, giving you confident control over tone and presence without sacrificing fitment or serviceability.

SS vs Inconel

• Stainless steel and Inconel are both corrosion-resistant staples in performance exhaust work, but they behave differently under extreme heat. Stainless is the practical choice, tough, dependable, and generally producing a deeper exhaust note. Inconel is a nickel-based superalloy that holds its strength and resists oxidation at much higher temperatures, which allows for thinner-wall tubing. That thinner construction trims weight and reduces heat soak despite the alloy’s higher density, and it tends to produce a crisper, higher-pitched sound.

Complete the System

• Tailor the Voltage exhaust for the Lamborghini Aventador SVJ and Ultimae around your goals for tone, weight, and longevity. Headers are available in T304 Stainless Steel or aerospace-grade Inconel, and pair with High-Flow Race Pipes in the same materials to open up flow and throttle response. Hex-profile Exhaust Tips in Stainless Steel or Titanium round out the setup, offered with Round or Polygon outlets; Titanium finishes come in Full Burnt Blue or Matte Black with Burnt Orange accents. A dedicated Error Canceller is also available to help keep check-engine lights at bay when race pipes are in the mix. Every component is built to vehicle-specific geometry with OEM-style connections for clean, repeatable fitment.
