Same unusual noise
 

Sorry, didn't notice this was the v6 section...
Hey
Similiar noise, I have a change in tone *buzzing* sound from the exhaust on my 2006 hemi. It sounds like the change happens I'm guessing when motor goes from 8 to 4 cylinders. Is there anything I can do to get rid of annoying sound other than goose the pedal or drive around with the O.D. turned off?
thanks,
Illiniwag

get a diablo predator, as I understand it you can turn off the mds with it
