1965 +4 tells Me that this tail pipe has been changed before. My exhaust specialist welds this stuff in. Cheap and easy ----FOR HIM to replace.
Exactly. Zero chance the system is the one it left the factory with and the way to start is to have a good look at what is there. But
do not weld exhaust joints on a Morgan. The chassis flexes, and if the exhaust is rigid - it'll break sometime. Indeed the incorporation of a flexible section or a slip joint as might be found on a rally car is a good idea.
