The muffler and tailpipe were dipped at the factory in a liquid ceramic material and then fired at a higher temperature.
After that, the muffler was wrapped in asbestos followed by a galvanized steel shield.
So sure was AMC that the muffler and tailpipe were ironclad, they were guaranteed against rusting through as long as the original owner had the car.
This was done as early as the 61-62 Rambler, and as late as the 66 marlin
And by the late '70's AMC dealers were replacing those exhaust systems practically annually. We no longer had ceramic systems, so they were replaced with stock steel ones, which rusted away fairly quickly on those low milage, short trip only Ramblers!
ReplyDeleteWas the entire exhast pipe ceramic coated or just from the muffer outward?
ReplyDeleteTony, I wrote in the article "The muffler and tailpipe were dipped at the factory in a liquid ceramic material and then fired at a higher temperature. After that, the muffler was wrapped in asbestos followed by a galvanized steel shield."
DeleteI don't know if that answers your question, but I can tell you I know nothing from 1st hand experience, as I never had one, I can only say that if you can not find the answer in what I posted, you might from using Google. But I have no idea. This is one of 57000 posts I've made, I just find and share stuff, I am no expert on the material, just in finding things of interest
