I have a similar situation on a D14. There is a chunk out of the manifold where the muffler goes into the Xhaust manifold. I still have the part, and was wondering if it would be possible to JB the missing part, as well as a pipe of some sort into the manifold? Also, what size of pipe would fit, and should I use cast iron, or some typt of exhaust pipe from a muffler shop?
Thanks in advance.
