Aftermarket everything? Whatever - you can wen cold just quick get it to idle and plug tail pipe(s) a bit and feel for leak if not obvious. If rusty in general you may need new something headers or not then so on. Rust can make leaks anywhere.


IDK - If this is all custom the "Muffler" {so called} specialty shops can be good at all this making up pipe or whatevers if not known factory parts it's going to be a challenge IMO,

they are cast iron exhaust manifolds- they will look rusty especially if OEM.
do as tom suggested on cold engine have someone restrict tail pipe (hold a rag) while you find the leak -
old rusty exhaust work - if you do not cuss now you will soon enough....


ram head was a desirable OEM exhaust manifold shape ... CONSIDERED almost headers.
