NEW: Lamborghini Aventador R&D Notes

The Lamborghini Aventador was introduced in February 2011 and marked a revolution to Lamborghini’s V12 platform evolution since the 1964 350GT by releasing its brand new V12 architecture. Producing close to 700hp, it’s the most powerful V12 production Lamborghini ever made. The new engine design radically changed the classic Lamborghini V12 sound. Supersprint recently got their hands on an Aventador to explore the performance and acoustics boundaries of the Aventador’s exhaust system.





Stock Exhaust

Due to ever increasing emissions requirements, the Lamborghini Aventador is heavily restricted from the factory. The stock headers are a four (4x) 3 into 1 configuration that merged into two (2) front sections. The front sections have four (4) ceramic catalytic converters that weight in at 14.9kg. The final section of the stock exhaust is a massive valved rear muffler with two (2) secondary catalytic converters integrated within the body along with 4 exhaust tips, the rear section comes in at a heavy 28kg.

As the stock headers are already well designed, our main objectives in the research and development of our Aventador exhaust system was increased performance, improved sound characteristics while retaining the OEM valve control compatibility, and finally, drastically reduce weight with optimized piping configuration.




Supersprint Y Shaped Front Section

Upon examining the 4 OEM catalytic converters on the front section, we saw room for improvement by increasing the cats efficiency by replacing the 4 OEM ceramic cats with 4 HJS, German made, racing metallic catalytic converters with 100 CPSI instead of the restrictive 400 cell OEM cats. The HJS metallic racing catalytic converters still offer optimal emissions control as well as retaining all OEM 02 sensor bungs and mounting points.

We were able to reduce weight by 2.6 kg, 12.3kg versus the OEM 14.9 kg. For those that seek ultimate performance and sound, we offer catless Y pipes which reduce the weight by 6.9 kg, weighting in at 8kg. These are for race usage only and will require a ECU tune to remove the Check Engine Light (CEL).




Supersprint Rear Section Options


Valved Rear Exhaust

The valve-fitted version of the Supersprint rear exhaust was designed to maintain the dual loud/quiet functionality. The valves are connected to the OEM pneumatic control pipes, the factory electronic management system is retained.

Our exhaust design and configuration vastly differs than the OEM counterpart, the Supersprint system in opened mode is a straight through direct design, with just an x-pipe that connects the two main lines for a better power. We tested multiple variations of straight, X and H pipes, we ended up choosing the X pipe for smoother power delivery and sound characteristics. The closed mode is made of a direct flow muffler with a individually researched and developed x-pipe.





In addition to our specific X pipe design, we removed 2 cats from our design to eliminate excessive weight and increase performance while still retaining full compatiblity with the OEM computer witout any Check Engine Lights (CEL). Our valved rear section weights in at 20kg, 8 kg less than the 28kg stock exhaust.



We retained the 4 single tips design due to the valve system layout. Their shape is round, with a slightly flattened top and bottom. They remain inside the OEM outlet, integrated in the bumper, but the trained eye can easily see there’s a special component behind it.



X Pipe non-valved

The rear “X-Pipe” design is very simple and light. It sacrifices the valve functionality in favor of the most aggressive, race-car like sound. We retained our specific X pipe design with removing the valved silencer configuration for optimal power delivery. At approximately 6 kg, it’s a massive 22 kg less than stock.



Performance Gains

The performance gain with the metallic cats and valve system compared to the stock setup, measured on our in-house MAHA dyno, is:

+ 11 hp of peak power at 8200 rpm
+ 11,6 hp @ 3000 rpm
+ 10,2 hp @ 6300 rpm
+ 12,2 hp @ 7400 rpm

+ 11,2 nm of peak torque at 5850 rpm
+ 27,6 nm @ 3000 rpm
+ 11,9 nm @ 6300 rpm



Ultimate Sound

When fitted with our catted front pipes and rear valved section, the sound is deeper, meaner and more aggressive in both modes. The onboard drone and road noises remain low in closed mode thanks to the adequate sound proofing of the cabin and Supersprint’s silencer design. Additional videos to be added.

I could listen to this for hours. Infatuated with the cabin sounds.

Is this build compatible with the UGR TT system?

Thanks for the comments guys!

No, UGR builds a new exhaust from scratch and re-routes piping for their TT kit!
