2007.5 6.7 Cummins Exhaust manifold replacement

[1BADDREAM]

68k miles and has had DPF/EGR delete for about 2 years. Now I'm getting a louder whistle under acceleration. Found out it's leaking from the exhaust manifold and needs to be replaced because they tend to shrink. Most of the 68k miles have been towing so while it's not a lot of miles it is harder miles. I am wondering if people have tried aftermarket manifolds and what kind of success they've had. I'm not looking to spend over $1k on factory parts that will do this again. I have seen an AFE ported manifold that seems to be good but don't want to waste a bunch of money. Any help on this would be appreciated.

here is the link for the AFE I found: https://www.rpidiesel.com/products/...derunner-ported-ductile-iron-exhaust-manifold
