4.0 exhaust manifold breakage cure?

Does anyone have the cure for this problem?"Ive removed my 97 oem exhaust manifold and welded it up twice but it kept breaking.I was told that they were redesigned so i replaced it with one from my local auto parts store and it has lasted almost a year and guess what its done it again.This jobs isnt the funest in the world 2 do so if anyone could enlighten me on this subject it would be highly appreciated.

Mine has a little leak and the best fix is a header from banks or a good aftermarket brand and they are not cheap that's why is still leaking

Get the 2 piece cast iron one from a later model TJ or a header with an expansion joint. Either one may break again though, sixes have this issue from being so long.
