Default Exhaust for the Speedster - Let the Singing Begin!

Before lots of guys say, “it’s to early”, stop and be greatful this isn’t a value thread.

We know now the car has the PF and side delete, so does that mean:

1) only a center bypass can be fitted? If so will a new design likely be needed vs one for the GT3?

2) a full exhaust system install is unlikely without the need for a remap?

3) what does electronic valve control mean vs vacuum? Is this the end of the annoying 4K transition?

It means for $300K it better be epic out the door.

Was thinking the same. I guess my new Graham Rahal Performance center bypass will not be an easy swap from the gt3 touring to the Speedster.

The current PSE is electronically controlled. A vacuum operates the valves, but the vacuum is controlled by the ECU and a solenoid/valve..

Interesting seeing the addition of a couple of NACA ducts on the rear diffuser for the car.

the vacuum is controlled by a electric valve, which controls the vacuum that opens the valves. An electronic solenoid would not last long being exposed to the heat of the exhaust.

Think of it this way, the center console has a switch that switch is electric to open/close the valves. And the valves are controlled independent of the switch setting by the ECU.

NACA ducts seem to be aimed at newly positioned PSE valves...
