DCE™ Mufflers
Sometimes you have to be quiet – and sometimes you want to be LOUD!

 

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 most other vehicles. There are (2) criteria to be able to use DCE™ mufflers.

1.) You need sufficient space for the muffler(s). The smallest version is (case length X case width X case height) 14” X 9 ¾” X 4 ¾”. Allow 3” on both ends for the inlet, vacuum actuator and outlet.

2.) For high performance engines, your vehicle must pull at least 14 inches of mercury vacuum.

 

The universal DCE™ Mufflers are available in 14”, 18” and 19” case lengths, with offset inlets and offset OR center outlets. Available inlet and outlet diameters include 2”, 2 ¼” and 2 ½”. They are a direct fit for a wide variety of AMC, Ford, Dodge, Plymouth, Mercury, GMC, Chevrolet, Buick, Oldsmobile and Chrysler cars and trucks. They are a modified fit for most vehicles.

 

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. In general, you will get the greatest sound contrast with the longer mufflers, so order the longest size that will fit your vehicle.

Some of the vehicles with DCE™ mufflers to date include: 1930 Ford Model A street rod, 1950 Chevrolet truck, 1963 Plymouth Fury Sport, 1968 Ford Mustang, many GTOs, LeMans, Tempests, 1974 Lincoln, 2005 Chevrolet Silverado and 2008 GMC Sierra. You can either hear them in most states, throughout Canada, in England and Australia or be first in your in your town or car club.

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.

DCE Quiet Mode Flow path

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!

DCE Open Mode Flow Path

 

You’ll love the way they sound!

 

Engine speed QUIET MODE OPEN MODE
Idle (750 RPM) 77dBa 84 dBa
2200 RPM 84 dBa 99 dBa
3400 RPM 88 dBa 100 dBa
Throttle “blip” peaks 90 dBa 102 dBa

 

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.

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

Universal DCE™ mufflers have less internal sound absorbing materials, so they 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.
