Default Re: 70 GTO question

You need an extra arm putting in the upper seal and pan. I asked some questions regarding the VOE set up. My info which came from Kirban and sources some 12 -15 years ago may not be correct. I spoke to GTO_Don who asked Jim M about this topic it seems you could get both options together. There is even a RA IV that has the VOE and Ram Air options. It was such a short lived option due to states complaining about noise levels that many people did not know about it. What a killer option to have on a Judge!

I wonder which RAIV GTO VOE you speak of? I ask because I know of one and it's a dealer-installed car. I'd be willing to bet this is the same car.

BelAir, they use a former heater/ac vacuum actuator to pull a rod that opens a valve inside the muffler letting the exhaust bypass two of the pass tubes internally. Essentially, it is like running a straight pipe and a very very quiet perf. muffler and being able to switch between them using a vacuum switch.

And here is a bit of data on how the 2" in, 2.25" out versions worked on my 69 340 Cuda and a shot of the car they are on, a true 70 VOE GTO four speed.

1969, 340 cu. in. 10.5:1 Chrysler engine in Plymouth Barracuda with 2.25” stock, 1969, 340 tailpipes with large rectangle chrome tips, measured at 10 feet from tailpipe outlet.

Closed Open
Idle (700 rpm) 68 dBA 78 dBA
2200 rpm 81.5 dBA 92.5 dBA
3500 rpm 88 dBA 99 dBA

They sound very good.

Belair62, here is a closeup shot of the inlet so you can see the actuator and how it attaches.

And here is the shot of the mufflers from the rear so you can see the spring portion; stand by for one more from the front.

And here is the last shot showing the overall front configuration... We are currently finishing one more "stock set" and then will build one custom set for a local street rodder. Later this summer, we plan to build a handful more for our own cars and a couple of musclecar enthusiasts.
