Driver Controlled Exhaust (DCE) muffler

For a brief period in 1969 & 1970, GTO buyers were able to purchase an option known as “Vacuum Operated Exhaust”. It was one of the industry’s most unusual options; dual-mode mufflers - controlled by the driver - that could be operated in “Quiet” or “Tiger” (Open) modes.

VOE-2™ Model
(For 70-72 GTO/LeMans/Tempest)

The VOE-2™ model is a close reproduction of the original GTO VOE muffler. It is also a “direct fit” for any 1970-72 Pontiac Tempest/LeMans/GTO with dual exhaust. If you are lucky enough to have a GTO that was originally equipped with the VOE option, with or without Ram Air, you can restore the VOE function by purchasing the mufflers only, without the control kit.

DCE™ Universal Model
(For almost everyone else!)

Waldron’s has a patent pending design that provides the look and sound of the original VOE Muffler for other vehicles. The universal DCE™ Mufflers are available in 14”, 18”, 19” and 21” case lengths, with offset inlets and offset OR center outlets. Available inlet and outlet diameters include 2”, 2 ¼” and 2 ½”. They will fit a wide variety of AMC, Ford, Dodge, Plymouth, Mercury, GMC, Chevrolet, Buick, Oldsmobile and Chrysler cars and trucks.

And of course, they can be utilized in most street rod or hot rod applications!

Universal DCE™ mufflers are slightly louder than the VOE-2™ model in the Quiet mode. In the Open mode, they sound and flow the same as the VOE-2™ model.

Disclaimer: Waldron’s recommends that you verify your local sound ordinances before driving in OPEN mode to avoid tickets.

Some of the applications for the universal DCE™ model:
68-98 Mustang (exc. 74-83)
70-73 Corvette
64-84 Most GM full size including Buick, Chevrolet, Pontiac & Oldsmobile.
68-85 Chevrolet & GMC Trucks
60-80 Most Chrysler, Dodge & Plymouth
68-76 Thunderbird
66-71 Ford Fairlane & Torino
67-71 Mercury Comet & Montego
79-85 Dodge Trucks
66-71 AMC
And many many more—Check the muffler check the DCE Application Chart for direct fit applications.

QUIET MODE: The muffler functions as a normal, triple-tube muffler with a double reverse flow pattern. Exhaust gases flow into the inlet, return forward past the front baffle and reverse direction to enter the outlet tube. Internal tube configuration and sound absorbing technologies keep the “Quiet” mode sound levels at approximately 70 dBA @ idle. In this mode, your car is quiet; inside and out.

OPEN MODE: Pull the “Loud” switch, and a valve inside the muffler opens to allow the exhaust gases to flow from the inlet tube directly to the outlet tube. This was Pontiac’s “Tiger” mode. Sound levels are typically 78 to 80 dBA @ idle in this mode. You hear a lower, deeper exhaust note inside the vehicle and the sound outside is approximately TWICE AS LOUD as in Quiet mode. Best of all, the exhaust flow rate is 37% higher than Quiet mode!

You’ll love the way they sound!

Through our co-operative efforts with Tom Hand and Jim Hall, the inventor of the original design, we are proud to offer a NEW generation of these mufflers.

The mufflers are available (individually or in pairs) by themselves OR in combination with a control system.

The double wall outer case, end caps, baffles and moving components are stainless steel. The vacuum actuator, which operates the valve, is mounted externally and is made of zinc-plated steel. Internal tubes are Aluminized steel or Stainless Steel, depending on the model.
