New member here. Anyone have any experience with aFe headers on a 24v?

It is a nice looking piece. Hopefully someone has used it and will chime in.

The only thing bad about the one piece manifolds is that they are more prone to eventually cracking either the block or the manifold at the mounts because of the manifold getting hotter than and expanding more than the block. More so if you have high egt's. The 3 piece manifolds were developed specifically prevent that problem. The joints can move during high heat preventing a load across all the block flanges at once.

That's the AFE ductile iron Bladerunner, I run one myself...very heavily built and flows good too, I checked it on a flowbench compared to my ported stock exhaust manifold. Ran better on my engine up the Test Hill I use.

Did you ever pull the trigger on the stainless header? Curious about cracking and discoloration.

My experience is on a 1996 12 valve. I bought on July 30-31 2019. Overall a very nice piece, very solid. My dislikes at the time were only 3 items.

1st, on the front runner between 2 and 3 the manifold looks like it was ground down for some reason. Very ugly looking. I contemplated returning it for another but figured since i was putting a blanket on it, it wouldn't matter in the long run.

2nd, after have run it for a short period of a couple months, just a couple thousand miles if that, the whole thing is a red/orange rust bucket of a manifold. More unsightly than the stocker. Even the spacers they sent are rusted up.

I am in the midst of doing an overhaul on the engine, so I will be sand blasting the manifold and spacers, then painting them with grill paint, or DIY heat coating. Just something to make it look better. I still have the blanket on it, but the blanket doesn't cover all of it.

3rd, the EGT threaded bung is too small. I can not put my EGT probe in the manifold using their spots. I have it in the elbow of the turbo right now, but will be drilling and tapping the manifold to the proper size. It was frustrating to find that out during the install.

I wanted to avoid the cracking/warping/rusty style, and went with a Stainless Diesel manifold. Very pleased with it.
