Lamborghini Aventador Exhaust Sound: Valves Open All the Time

While performance cars are getting faster by the day, with track records falling like they had been set by toddlers, there’s one are where these vehicles haven’t progressed: the audio one. Many go-fast cars sold today don’t come with a soundtrack that matches the performance and when we’re talking about a vehicle like the Lamborghini Aventador, this can be quite an issue.
The Aventador’s V12 engine uses an exhaust that comes with an active valve and while at high revs and during generous throttle applications this does allow the powerplant to make itself heard, in the lower rev area, which is the one you usually use for your daily city travel, you never really feel you’re driving a V12. Of course, you can turn to aftermarket exhaust, but this usually also requite an ECU remap and this can bring warranty issues and is also a costy option.

However, there is a much simpler way of making your Aventador truly sound like a V12 supercar: you can fiddle with the valves in the exhaust, making them keep the “open” position all the time, as one luxury4play member, who is an Aventador owner, discovered.

The Lamborghini dealership that sold him the car removed the flat underbody protection, fiddled with the exhaust valves so that they would allow maximum flow all the time, put everything back together and now the vehicle sound great even at low revs / speed. What they did under there was to remove the vacuum lines from the valves and plugged them. You can hit the “play” button above to see and hear how his Aventador behaves after the little tech play.
