This is what now sits under my hood.

If I understand correctly the reason the factory exhaust manifold shrinks and cracks is the metal it is made of. the factory exhaust manifold is made of cast iron which shrinks with heat cycles.
The options for replacements seem to be a 3 piece exhaust manifold which can sometimes leak at the seams, stainless one piece which is horribly expensive, one piece made from cast ductile iron, or a factory replacement which will most likely fail again and again.
I have read where ATS 3 piece exhaust manifolds have cracked. I do not know if this is an ATS issue, people running to high EGT's or a common 3 piece problem.
I am not into hotrodding my truck. I want it to be a reliable tow rig and perhaps daily driver. I may eventually add a 10 plate and 5x.011 injectors and perhaps add a hx35/50 hybrid.
I am still shocked that a stock truck could have a shrunken exhaust manifold at 120k miles. Now I just need to figure out what manifold or at least type of exhaust manifold is best.
This is a cheap 3 piece unit.

This is not much more expensive for a 1 piece unit.

This is a slightly more expensive stainless piece.

I know about steedspeed and stainless diesel but those are much more expensive.
Can anyone give some useful input on choosing a replacement part?
