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.
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.
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.
Material: Premium T304 stainless steel with a stunning anodized gold finish for heat resistance and visual impact.
Weight Savings: 27.1 lb lighter than OEM, improving handling and responsiveness.
Manufacturing: Fully mandrel-bent tubing and precision TIG welds ensure maximum flow and long-term durability.
Fit & Finish: Reuses factory exhaust outlets for a clean, OEM+ look.
Reversible: 100% bolt-on installation allows a return to stock at any time.

Instructions are included for most parts that require any sort of knowledge to install.
Here's what to do if your parts come WITHOUT instructions:
1. Some parts are genuinely common sense on how they get installed
2. If you can't figure it out on your own, YOUTUBE IS YOUR FRIEND! Our founder started this company from learning how to build headlights off a YouTube Video
3. If there are no videos on YouTube, or instructions anywhere on Google then please CALL OR EMAIL US and we will guide you through or get you instructions from the manufacturer
4. Doing installs on your own is always fun, but sometimes, it isn't. Always consider having your parts professionally installed
ALWAYS CONSIDER US. We sold you the parts, let us install them at THE LAB in Connecticut. We offer enclosed and open cross country transportation.
Of course you won't want to spend thousands on transportation to install lug nuts or emblems but if you are spending a LOT of money on parts, you may just want to send the car our way
If the part was NOT installed, we accept returns within 14 days of delivery.
If the part WAS installed (or attempted installation), we cannot accept a return.
All parts come with Manufacturer Warranty! Each manufacturer has different warranties so we suggest reading up on their warranty policy before ordering.
YES! If you come across a competitor with a lower advertised price than us, we will BEAT it by at LEAST 1%. Please contact us with proof of the lower priced product.
NO! We do not give out discounts or do sponsorships. You can get 5% OFF your first order by signing up for text & email notifications. OR just wait until our BLACK FRIDAY Sale that happens once a year.
