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 GTO "Humbler" with VOE; ca: 2007
New generation VOE mufflers on VOE GTO 1970. Camera cannot show it but sound differential is 10 dBA plus between loud and quiet.

71 LeMans Station Wagon at Strip, Run #9, 11.56 at 115+ mph
3.31 gear, 4070 pound, Q-jet, Goerlichs X-141 mufflers, GTO appearance package, Dr. Gas X pipe, Dr. Gas ovalized tailpipes, exit on passenger side, 11.56 at 115 + mph. Please note, track cleaner is running and sound from its single cyclinder Exhaust is almost louder than Exhaust from the wagon as it runs 11.50s at 115+ MPH. This is truly a very quiet car.
1965 Chrysler New Yorker 440 Cold Start
Here's a cold start with the Waldron dual Exhaust I installed this Summer. They gaurantee fit and it went on nicely. The kit is listed for a '65 300, but after poking around I determined the NYer has pretty much the identical C Body and was provisioned for duals. I opted for the 'Imposter' factory replacement mufflers which have a noticeably loader note. My cinematography blows but I hop you like the vid anyway. And yes, it is a factory 440. One of the early ones pulled ahead from the '66 model year....
'69 Cuda 340
TTI Headers and 3" pipe w/ Dynomax Race Magnums (Ultraflos). Camshaft is Whiplash from Hughes
Plymouth Barracuda Hemi
I believe a 1967-69? I never saw the engine. This was at the 2007 Turkey Run at Daytona International Speedway. (last one I've been to, haven't been to any others because of other shows or couldn't get the time off)
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.

Comparison of Magnaflow Mufflers and Stock Mufflers and a lil clip of what it sounds like without mufflers.
1965 Chrysler New Yorker
Dad pulling the Chrysler around to put her on the Globe Hoist. I always use the park brake since the I never trust the park pin to hold the 4800 pounds in place. The Waldron Exhaust sounds pretty good.
Waldron's Reproduction of the 65 Mustang "Arvinode" exhaust
For several months of 1965 Mustang production, High-Performance "K"-code Mustangs were equipped with a unique dual Exhaust system. This system has not been available to Mustang owners since the late '60's. Waldron's is proud to have worked with Dave Wallace and a number of other K-Code owners to bring the system back. Have a listen!
1969 Cuda
2/10/2009 Steve's 69 Cuda out for the first spin in the driveway at Dirt Dobber Classics after receiving a complete restoration. The engine is a 440 CI with a 727 automatic. The car was painted back to match the original F3 color. The car is a true S code 383 car but the original engine was not available. www.dirtdobberclassics.com
