Can I just remove my mufflers from the 997S and bolt on the PSE mufflers or do I need anything else? The valves that are controlled to open and close for the sound is my worry. If you install the mufflers and nothing else, are they open by default? How does it work since they would be controlled by the electric unit. How about the vaccum hose? Thanks!

The pse can be installed w/o the electronics. It stays open all the time. Do a search to find reams of discussion about this in the last couple of days.
