Lamborghini Aventador - revving with Supersprint exhaust

Car fitted with:

-4x HJS catalytic converters in place of the OEM main cat, 1 for each 3 cylinders.

-Secondary cats integrated in the stock rear exhaust removed by a new system with bypass valves.
Straight through exhaust with open valves (with x-pipe), free flow silencer with closed valves, louder than stock in both modes.

Full 304 stailness steel system.

682 hp as stock, 694 with new exhaust, measured on our in-house Maha 4x4 dyno.

Sadly no road test video or video at night...

Yes it's the same. On that video the valve were functional, on this we were testing the two modes quiet/loud using caps to block the louder route.

Both videos were shot with the car in perfect working condition (oil in temperature etc). The way the gas was pressed may be a bit different, because two different people were on board. The digital dash has some delay relative to the actual engine rpm, that's evident the inside shots. Also consider the other one was made indoor, while this is outdoor (for the second part).

Do you need to know for track use? We didn't measure the flybye db level but it's quite loud on full throttle, as much as it can be.

the sound in the linked video sounds amazing but in this video it sounds like the car is struggling to operate the gas input, sounds like the car is being tortured. I like the exhaust but why do I feel the two videos very different from a part? Was this maybe in early development stage?

[grosano]

Can you misure the dB? How loud is it?

[ijustinw]

is this exhaust the same as /watch?v=ip5UXTDPyWo?

Mi piace perchè non fa gli scoppietti in rilascio come gli scarichi di altre marche

cant even afford the exhaust system for this car but i still like to pretend i'll own one in the a decade or so
