Exhaust manifold upgrade?
Based on second hand info I ordered online a manifold for a newer model that has the "bellows" in the #1 and #6 cyl pipes for my 93 4.0L ho. I would really like to hear from someone that has actually put the later model manifold on an older engine before I try to tear it apart. I am disabled and it is going to be about all I can handle so I want to get it done the first time.
Can anyone help me with this?
Thanks.

I put a MOPAR one on my '92 H.O.
The accordion folds supposedly give the manifold room to expand, thereby reducing the likely hood of cracking. My old one was badly cracked when I bought it.
I used OEM because I didn't want any matching up or mating issues that might be caused by sloppy aftermarket ones.
It wasn't cheap, but I'm glad I did it. No problems whatsoever.

If the newer manifold has two 02 sensors....Well if it's going to be inspected I might be careful that your single upstream 02 is located somewhere to catch all six. Just a thought, Idk if that's a real issue or not.
