Every now and then I get to brag about my Vacuum Operated Exhaust (VOE) mufflers I built (and am still building). I just got done with six pair for Pontiacs and I test them on my '69 340 Barracuda 340-S. While my set was off for testing these others, I shot a few photos of them to share...

This will show you where my VOETOM came from, the car that started and eventually ended up with the muffler I build, and you can see the display I made for the VOEGTO at MCACAN in 2021. What a cool car, awesome exhaust, and fun project!!!

Here is the real car from the 1970 Super Bowl commercial running the new VOE mufflers we have been making. I know it is not an A body but I run these on my 69 Barracuda so it sort of fits in. I know you all can appreciate such a unique car and it was awesome hearing and seeing it live.

Pulled these out of storage and took a few images in case anyone forgot how choked the stock systems were.

Kevin Jonker A friend of mine, Kevin Jonker, has been working on this cutout design for a while and sent me the link to his new website. I think it is a pretty neat idea and wanted to share it (but sorry for posting the wrong address originally). I must admit I have never tried one since my...

Playing around with some paper and cardboard and fabricated some 19" by 5" by 11" offset-center mufflers with 3" inlets and outlets. Going to use these to test fit on a pal's car. Tom

I have two Dynomax Race magnum header collector muffler assemblies to donate to a new home. You will need 1.875" header tubes terminating with 3" outlets. These are coated and new. I'll donate them if you plan to use them but not resell them. Pay for shipping and help clean up my basement. Tom

Recently acquired lots of new mufflers that were dyno tested but they are now in my way in the basement. I am donating them to needy owners for the price of shipping IF you are going to use them and not resell them. I have some offset inlet, center outlet , 2.5" in and out Terminators and...

Got bored again and needed to make some mufflers for a pal to tone down his non mopar currently running chambered mufflers. Check these out. They sound very smooth, very tame, and will flow a lot of air. I used the max size case I could to fit in his under chassis area, 5" by 11" by 17"...

http://www.musclecarfilms.com/Exhaust.html I have a really good friend that is great tester and I asked him if he'd mind running some tests of the new Dynomax Vt mufflers on his 69 Firebird. If you are interested, his website has lots of images and data regarding sound testing and comparisons...

Here is a current rear shot. Stock tail pipes expanded to 2.5" with stock OEM tips. Tom

Greetings, we have been doing a lot of muffler testing since about 1988 on big Pontiacs and our 340-360 cars. Also, I have been playing with vacuum operated mufflers which are not meant to be race pieces but are great for those wanting a dead stock sound on the way to a show but want to be able...
