06 Z06 mufflers are equipt with what seems to be N/O vacuum actuated valves which bypass the baffles in the muffler making it a straight through exhaust. The valves open in the 3-4 thousand RPM range under hard excelleration. I have been told there is a fuse which can disable the valve leaving it open at all times. However I don't know how its labelled or where it is and also this seems contradictory to it being a vacuum operated valve. If its electric I would like to make it switchable for the long trips. Any ideas out there?
