Z06 or 08 Vette-what is controlling dual mode exhaust? What controls the dual mode exhaust butterflies in a 06+ Z06 or 08 C6 Corvette? I have HP Tuner but have been unable to fine any program function. The butterflies open approximately 3500 rpm. What or where do they get their signal?

I looked thru, i think it is just controlled by a whole different module, not the pcm. BUT it does recieve a rpm signal from the Can bus which originates from the pcm.
If you would like to make it turn on sooner/later, you can buy an rpm converter output box from the street rod guys that you can minipulate the rpm signal seen by the muffler module. But Yes they are correct also, as it being run off of vacume but controled electronically.

Don't want to pull the fuse. I tried that and it's too loud for most of my driving.
