This kit is connected to the original Porsche beam and allows the automatic shut-off of the valves between 45 and 75 km / h, while keeping the PSE button on the center console.
This break exists at Porsche 996, 997-1, 997-2 and the Boxster of these generations.
Small history: To homologate an exhaust manufacturers must make a dynamic test between 50 and 70 km / h. So Porsche put this cut of the valves between 45 and 75 km / h but without accounting for 3 things;
> This cut was not necessary for the respect of the sound standards which are always ok without this cut.
> Other builders (who have the same laws) did not apply it.
> It's punitive for drivers because it's the speed at which you get the most out of your car.
All this is so true that the Porsche no longer have this break from the 981 and 991-1 while the regulations have not changed.
