Anyone familar with CMI Split Elbow Tops? Cannot find them anywhere but see there are some faor sale in Classified's? ANy opinions or help would be helpful!

I have used several sets of them. CMI stopped building them many years ago. It has been well over 5 yrs. since thay built them as far as I know. They were excellent headers and probably some of the best they ever built. I have never had any trouble from them, nor do I know anyone that has. I would have them pressure tested before I would buy any used headers, especially ones that old. If they test good, I would not hesitate to buy them.
