Default Re: 70 GTO question

Now I anm confused about the VOE option. Tom Demauro's book quotes John Sawruck as saying that the VOE mufflers when actuated would reposition the baffles from the quite Lemans muffler tone to the more agressive stock GTO tone, and they were not available on Ram Air cars. But if a Ram Air IV car has it listed on it's paperwork somewhere I guess it got installed under the radar.

Hi Guys,

I have a few very interesting "Distribution Bulletins" regarding the 611 VOE Exhaust option on the GTO. The option was available on (STANDARD 400 engines only) beginning on October 21,1969. It was discontinued on December 10,1969 for GTO's headed to the State of PA. I have not found the bulletin regarding the availability in other States. I will post these bulletins if I can figure out how to do it. I have no idea how to do an attachment. Mike is correct and did allude to cars "under the radar". As with any Pontiac, you can never say never when it comes to options.

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!!

Judge Man,
I am building some new "VOE GTO" mufflers and would love to have copies of anything you might have regarding them. We are building them in other sizes to enable them to work a bit better when open.
Please, if you are still on this site, contact me if you do not mind.
Thank you.
Tom Hand

Belair62.
They are really cool. Sound slicker than heck too. We have a set on a 69 CJ 428 Torino, a 55 Chevy, and on a OEM GTO 70 VOE car. Two more sets go to real VOE cars, one on another GTO and another on a street rod and the final ones on a Truck.
Very labor intensive to make for sure but cool to have. I can get them together with up to 2.5" in and out where stock was 2" in and 2.25" out.
I have several photos. This set is a one-of-a-kind, offset-center, 2.5" in and out and they are on the Torino.
