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.
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.

Finally the F1 sound I NEEDED
"So happy I went with this set up, the system arrived extremely quickly my shop was able to install really fast and I love the sound When I got my SVJ, everybody told me to go with the gintani set up, but I was going to have to wait 8 to 12 weeks for exhaust is too long. I called valvetronic and pierce and his team got me pointed in the right direction and told me that the sound would be as good as anything else on the market and it’s in stock ready to ship. I pulled the trigger and They were nice enough to overnight it for me. The sound is silly, I compared to my friends, gintani SVJ and I prefer the depth The valvetronic system gives compared to the gent. Even my friend with his car agreed he thinks mine sounds better. Very happy with the level of customer care and product quality to come out of this company. First time buying from them, and I will definitely be buying systems for my future cars. highly recommend"

Q&A
Do you guarantee no check engine light?
for just the rear section, yes. If you add the free flow race we do recommend a tune or spacers
