HURACAN 580/610: Race Exhaust

[6102Perf]

I did some decibels tests today and now I'm convinced I have a race exhaust.

Standard exhaust 88 dB
Sports exhaust 92dB
Race exhaust 102dB

Background story, the original owner had a ton of money from an inheritance from his wealthy father. The guy also raced cars and last he took every option available when he specced the car. This part is a theory of mine he might of test driven the press car that had a race exhaust on it and wanted one installed, same dealer, only a few months apart of the production build. Specs of the cars are almost identical.
At the few car shows I attended my hearing lead me to believe my car was way louder than the other Huracans and now I can confirm it.

One of the test, I tied the decibel meter on the back grill, I drove around twice but I couldn't get a reading because the meter turned off. The meter must have an automatic shut off after a few minutes. I will try it again on a short stretch.

Here are the results of the other tests I did.

Accuracy of the device :
+-1.5 dB (94db@1KHz)
+-5 dB (94db@8KHz)


Overnight cold start 116.3 dB

over an hour drive, I parked the car and tried to gently rev it to 5000 rpm and got 119.5 dB

Then I tried inside the cabin with windows down while accelerating to 70 km/hr. I was holding the meter at the window, 116.3 dB.

This test that I will have to try again, the device kept shutting off. However the instruction states you can select to save data, I'll try that next drive.

Very cool, that's a good reading! Do you have any sound clips you could post? I know the race exhaust very well it has quite a distinct tone. If you posted some clips I could tell you if it sounds like mine did.

I'm not sure a phone has a good enough mic to prevent distortion. I would have to dust off my minidisc with sound mics and custom made amplifier specifically to record loud music. I recorded many concerts with it feeling like a spy bringing it inside while security guards checked every one coming in. Once inside rearanging the device and mics so they wouldn't see them like those informants on TV show wearing a wire.
