Listen to a Ferrari 458 Speciale Hitting a Painful 126 dB with a Custom Exhaust

While Maranello’s engineers have already tweaked the 458’s exhaust for the Speciale treatment, the aftermarket world will always be willing to come up with an even meaner soundtrack, so here we are, talking about a custom Speciale exhaust system that comes from Fi Exhaust.

The Taiwan-based exhaust specialist got its wrenches on a Speciale, installed its hardware and then strapped the supercar to a dyno. Sure, the aural result is more of a subjective matter, but, in order to make sure things remain objective, the team brought a sound level meter into the dyno room.

Just like the stock exhaust, the Fi one comes with valves, so the company measured the noise level with the valves closed and then open. The Ferrari was revved to 5,000 rpm and, in the first setup, a maximum value of about 114 dB was recorded.

From the very moment the valves were open, the idle rumble of the naturally-aspirated 4.5-liter flat plane V8 became some sort of an elephant in the room and we mean that in a good way. The sound level? Up to around 126 dB.

By the way, 120 dB is the value where a sound starts becoming painful - we have to mention this is 32 times as loud as 70 dB, the sound of a passenger car driving at 65 mph (105 km/h) on the highway.

The 458 Speciale Fi Exhaust system

Fi Exhaust’s 458 Speciale hardware uses the aforementioned valves to allow the driver to choose between five levels of aural enjoyment. The systems weighs 47 lbs (20.95 kg), which means it’s around 6.6 lbs (3 kg) lighter compared to the stock system.

Still, if you opt for the tuner’s full system, this will include a catalytic system removal, which is now exactly what you’d call street legal.
