Lamborghini Aventador SVJ/Ultimae Catback Exhaust System(No Valve)

Unrestricted V12 Symphony — CEES Lamborghini Aventador SVJ / Ultimae Straight-Through Axle Back Exhaust System

Engineered exclusively for the pinnacle V12 flagships — Lamborghini Aventador SVJ and Aventador Ultimae — this Straight-Through Axle Back Exhaust System eliminates restrictive factory silencers to unleash the raw, untamed F1 scream of the 6.5L naturally aspirated V12. Available in two distinct acoustic architectures — Direct Connection Design and Equal-Length Z-Pipe Design — this system drastically sheds rear overhang weight while delivering an uncompromising acoustic experience.

🚀 Two Tailored Acoustic Architectures

• Direct Connection Design: Features an ultra-short, direct high-flow pathway straight to the high-exit exhaust tips. Engineered for maximum exhaust gas velocity, minimum backpressure, and the rawest, loudest, most aggressive V12 volume possible with violent overrun flames and pops.
• Equal-Length Z-Pipe Design: Incorporates a precision-engineered serpentine "Z" crossover geometry within the rear subframe. This tuned pipe length harmonizes exhaust pulses from the massive 6.5L V12, elevating the tone into an ear-splitting, razor-sharp high-frequency F1 scream while minimizing low-RPM drone.

🚀 Engineering Highlights

• Massive Rear Weight Savings: Eliminates the bulky and heavy OEM rear muffler assembly. Precision hand-crafted in your choice of ultra-lightweight Grade 5 Titanium for maximum weight reduction or heavy-duty T304 Stainless Steel.
• Master-Tier TIG Craftsmanship: Hand-TIG welded by master fabricators with full argon back-purging to withstand extreme V12 exhaust gas temperatures and sustained high-RPM driving.
• 3D Scan Precision Fitment: Engineered via high-definition 3D chassis scanning specifically for the SVJ and Ultimae high-exit center bumper architecture. 100% direct bolt-on installation using OEM mounting brackets.

FAQ

1. What is the sound difference between Direct Connection and Z-Pipe Design?

The Direct Connection Design offers the shortest path for exhaust gases, resulting in maximum raw loudness, aggressive crackles, and violent overrun. The Z-Pipe Design tunes the exhaust pulse harmonics through an equal-length serpentine path, creating a cleaner, higher-pitched, exotic F1-style scream at high RPM while reducing unwanted low-RPM bass resonance.

2. Will this exhaust fit both the SVJ and the Ultimae?

Yes. Both the Aventador SVJ and Aventador Ultimae share the same high-exit rear bumper layout and exhaust hanger geometry. This system directly bolts on to both models without modification.

3. What is the difference between Grade 5 Titanium and T304 Stainless Steel?

Grade 5 Titanium provides massive weight reduction right at the rear overhang of the car, noticeably sharpening handling balance while delivering an intensely sharp, higher-pitched exotic howl. T304 Stainless Steel provides exceptional structural durability and a deep, aggressive roar.

4. Are you a direct manufacturer?

Yes — CEES Exhaust is a direct manufacturer located in Guangdong, China. We engineer, TIG-weld, and quality-check all exhaust systems in-house to deliver track-proven performance directly to exotic car owners worldwide.
