Who produces the original drain valve

I'm making a terminal both in stainless steel and titanium but I can not find online who produces the electric valve that manages the exhaust gas discharge.

My emira has already given twice mechanical error of the valve limiting the exhaust performance, so I am forced to find an identical to make the new terminal.

I'm not 100% sure, but Janspeed produced the sport exhausts for the Evoras. So it could be them again.
