Where can I buy chambered tailpipes for my 67 442?

 

I found some for a '65 442 about 5 yrs. ago, in Stainless - somewhere in Ohio, I think, and they were a perfect fit!
Add was in Hemmings.

 

From JWO: Walt Vallelunga (586) 739-8255 waltvallelunga@yahoo.com Has 65-67 chambered tailpipes.

 

X2 Walt made these long before the other players got into the game and deserves our support. And the pipes are superb! Nothing better out there, either. Walt also sells "matching" front pipes too.
Highest recommendation.

 

Agreed on Walt. He's been making these at least 20 years and I think longer. Very knowledgeable guy on 65-7 cars.

 

Walt's 67 pipes...

 

For the "purist" I have one pair of NOS 66-7 tail pipes, but I am sure Walt's are good and cheaper.

 

To take us in a little different discussion, always thought it strange that Olds was the first to use chambered pipes (64 Starfire/Jetstar I) as well as the first to abandon them (67 or early 68 442 depending on your info source), just before Chevrolet figured out they might help a Camaro or Chevelle.

Ford used them briefly on early 65 K-code Mustangs (the "Arvinode" exhaust which Waldron Exhaust is reproducing) and again abandoned them before Chevy ever thought about using them. If I had an early Mustang, they would be on it.

Olds and Ford incorporated resonators in their chambered exhaust systems to quiet things down a little. Chevy did not, and the resulting loudass cackle caused a lot of state legislatures to outlaw chambered exhaust systems in response to the noise.

Virginia still has that idiot 1969 law on the books, but it did not slow me down from recreating a correct chambers/resonators exhaust on me green 64 Starfire. With the front and rear resonators in place, the car is astonishingly quiet unless you get into it- way quieter than I had expected.

 

corvettes where using chambered exhaust in 65....they where called side pipes, and where first optional in 65...

it is the only way the corvette could get them inside the covers and have ground clearence.....

 

I stand corrected on Chevy's first use of them. I tend to not think about Corvettes in the same sentence as a regular car. Besides, they were side pipes, not full-length under-the-car exhaust as the others were using, including the Camaro/Chevelle chambered systems.
