Here are two of our VOE-GTO mufflers temporarily mounted under a stock 1969 340 Barracuda. The microphones were close to the Exhausts' outlet, notice the 11 dBA change from closed to open?

Waldron's DRIVER CONTROLLED EXHAUST (DCE) mufflers
Listen to these mufflers on a 1971 GTO. Patterned after a rare Pontiac option, they allow driver control of a dual mode (QUIET or OPEN) passage in the muffler. These things are AWESOME!





1970 Pontiac GTO VOE "The Humbler"
A new and short-lived option for 1970 was the Vacuum Operated Exhaust (VOE), which was vacuum actuated via an underdash lever marked "Exhaust." The VOE was designed to reduce Exhaust backpressure to increase horsepower and performance, but it also substantially increased Exhaust noise. The VOE option was offered from November 1969 to January 1970. Pontiac management was ordered to cancel the VOE option by GM's upper management following a TV commercial for the GTO that aired during Super Bowl IV on CBS January 11, 1970. In that commercial, entitled "The Humbler," which was broadcast only that one time, a young man pulled up in a new GTO to a drive-in restaurant with dramatic music and Exhaust noise in the background, pulling the "Exhaust" button to activate the VOE and then left the drive-in to do some street racing. That particular commercial was also cancelled by order of GM management. Approximately 230 1970 GTOs were factory built with this rare option. A few mufflers have been "Hand-made" for the remaining cars; this occurred in 2006 and 2007.
