Porsche 718 GT4 AKRAPOVIC Exhaust + Cargraphic valves control

Akrapovic slip-on-race exhaust, Including OPF, gives the car a deep, racy sound.
The remote control of the exhaust flaps (in this case Cargraphic valves control) ensures the opening of the flaps even between 2.8-4K RPM, when Porsche automatically is closing the flaps even in the case of open flaps on the GT4 center console. You get full sound in the cab and outside even at lower revolutions.
The controller has 2 positions: 1-always open flaps 2-automatic control of flaps by Porsche (Incl. the possibility of their complete switch-off)
The sound was recorded using the Zoom H5 stereo recorder in the interior of the GT4.
Noise measurement: iPhone decibel meter

Read the Description…

[@miikavuorio6925]

Yup

[@GethinJames]

Audio doesn't sound good. May I ask why you're double clutching?

[@70vikingable]

I love engine exhaust sound but anything above 80db destroys hearing

[@yurenchen6431]

Opf itself is over

[@ronburgundy4375]

Arkopovic isn't all it's cracked up to be for 1 they focus on just purely being loud. 2 why have remote valves on a car that already has a button

[@miikavuorio6925]

Because the exhaust button in the vehicle does not open the valves for the entire rev range because of regulations so from like 2k to 5k revs (or something along those lines) the valves are closed no matter what position the stock button is at

@@miikavuorio6925 They open more like 4k rpm but you have the right idea.

Need a better mic or something. Audio is super low
