Z06 Mufflers
I am planning to use the C6-Z06 mufflers (when they are available.) I like the idea of built in 3500rpm cutout. Does any one know if that door is mechanical-ie no electrics or just just pressure. I am planning on using the Kook's headers and the 3" cross X pipes.

That's necessary because the valves are only supposed to open above 3500 RPM, so it needs a tach signal to determine when to act. The computer on the regular C6 doesn't provide that signal, but I suppose you could switch the vacuum manually.
