How the Active Exhaust Valves on a 2018 Ford Mustang GT Work

Research video from the R&D department at Borla shows how the Ford valves respond to rpm changes in all driving modes.

Yes! I have been waiting for a video like this. Any idea how it’s prioritized? Valve position based on RPM or load?

And here I was going to make my wife lay in the trunk with it open, holding on to a mirror.

Is the stock active exhaust system the same as the non-active system? If so, wouldn't this just reduce performance for the sake of suppressing sound? I'd rather move them before the resonators and have them act as cutouts to be honest.

No, the mufflers are different from active to non-active. I was surprised as well.
