I know this is an older post but has anyone tried these?

BladeRunner Ported Ductile Iron Exhaust Manifolds

OE exhaust manifolds are prone to cracking. These bladerunner exhaust manifolds features 25% thicker walls than the OE design, providing superior strength and durability. The added material helps withstand higher heat cycles and vibration without warping or cracking. Machined Ports:These...

I have been watching those for a while now before they even became available. I have been waiting to pull the trigger between these or the BD diesel, only 2 I would dare consider and so should any other person over stock/aftermarket ie dorman or shorty headers. I have 65k and nothing wrong with mine, but will be replacing very soon to stay ahead of it and upgrade performance while at it.

I'll be making a decision once I can verify if the AFE provide more flow than the BD as I suspect it may be the same and if afe hardware is the same as BD.

I know the BD are better flow design than stock on top of the construction etc, the known benefits, but they do not claim anything on flow and not sure they care to vs AFE does more testing than BD and does provide flow specs.

BD is a very well-known brand in the diesel world and solved the same issue that plaques HD trucks with manifold warp/bolt breaking so it is not a hemi thing and certainly not the only gas truck brand in Dodge with the issue if you do some research and pay attention... I trust BD so will be hard for AFE to beat unless the hardware is the same and the flow specs are better...

Side note: Banks Power is up to some engineering with the hemi's so wouldn't be surprised if some new releases hit in 2026, albeit exhaust manifolds are not in their wheelhouse, but they are designing an exhaust, so maybe headers too and hopefully a sealed cai...

aftermarket ie dorman

Have you looked at the dorman in person and seen the differences vs stock?
