The Ferrari 458 Italia F1 Valvetronic Exhaust System by Frequency Intelligent Exhaust takes an already euphoric exhaust note and transforms it into a sound only previously heard in a F1 race. Not only does this system make the car sound and spit blue flames under acceleration just like a car restricted to the track, but once the gas pedal is released, the idle sounds just as quiet and smooth as the factory exhaust. They accomplished this by using an exhaust valve, what they call Exhaust Valvetronic, similar to the OEM counterpart.
