I have only seen 2 actual VOE cars and both were GTO's and one was a chrome bumper car, The option was quietly promoted for obvious reasons. There was a vacuum actuator on the rear of each muffler much like the vacuum motor on a Chevelle Cowl flapper, Late in 1969 Pontiac made a TV add that ran during the superbowl, It showed a GTO rolling thru the drive-in, The driver reaches down and pulls the cable under the dash much like the RA cable and the exhaust note picks up and heads turn in the drive-thru!! Very cool, But Alot of people watching the Superbowl were not impressed,Including Pontiac Exec's, and the Monday after the Superbowl was the last day for the rare option. NOS parts for this option are very rare and most of the time must be hand made. I have seen only a few scattered parts NOS through the years and never an actual muffler, There's a repo project for someone!!
