Nice system.

I'm very interested in the longevity of the valve system. All of the aftermarket electronic "cutouts" are electrical (motors) and they all fail due to heat/thermal cycling (despite a lifetime warranty). OEM systems such as Ferrari and the other aftermarket BMW valve system use a pneumatic valve instead of electrical. From what I understand the pneumatic valves are really bulletproof from a maintenance and longevity period. Can you tell us a bit more about the valves you chose, why, what to expect for longevity and warranty?
