Is this a stock manifold or aftermarket header?
I assumed this is the stock exhaust manifold
Because it was on the jeep when I got it, but a guy that came by to buy some old parts from me said it looked like an aftermarket header. You guys know best so please let me know what it is. Also can it be welded? There is a very small crack in it that I'd like patched while I have it out. Thanks!

I replaced mine w/ an APN manifold/header. Ended up w/ two because one had a hole in it. Took both the stock manifold and the APN header to the exhaust shop and they hooked me right up.

I can try. It's a small crack but it seems around here it is tough to get someone to weld stuff. I have a shop that pressed some bearings for me awhile back. I'll visit them and see if they can do something.
It's cracked here:
When I tried to weld mine back in the 90's(88 XJ), I put too much heat to it and warped so when I went to install it, it didn't line up.
Thanks for the suggestion. I'd love to save the money vs buying new.

Welding is a band aid fix at best. It might last a little while, but it will crack again, right where it did before, or at the edges of the weld.
This is also the time to check your motor and transmission mounts...

I'm looking to build a reliable Jeep that doesn't have me constantly reworking areas because I took a shortcut. So far I have gone to OCD lengths in rebuilding this thing.
I may still ask about welding it and see what they say though I trust you when it comes to welding.

Don't get me wrong, welding can be done, plenty have done it, myself included. I'm of the mind of if you're already in there, have the header removed, just replace it. That way you KNOW it's good. It would suck to have to rip it all apart a year later for the same bull****. Ask me how I know lol
Edit: a manifold similar to this can be had for anywhere from 80-150 shmeckles online...pretty inexpensive piece of mind IMO

Stocker was cracked 3/4 of the way around the entire pipe collector where all the primaries all join at the bottom... and the motor mounts although looked fine when i took them out to replace while I was doing it, they crumbled apart and were the root cause

Used that same one from Amazon for $86 about four months ago.. .zero issues so far and fit/finish was perfect compared to the stocker it replaced.

I have been trying to ascertain if my motor mounts are good or not but really can't tell. They appear to be intact though they do not look perfectly centered in the steel. Could be that they are like that or it could be that I can't see the broken down rubber. Given that they are most like factory originals, it wouldn't hurt to replace them.
I don't think OEM ones are still available, not sure though, and aftermarket OEM type seem to be hit or miss.
Then all the upgraded ones, Brown Dog and etc, seem to be hit miss on the reviews.
Not the quality but vibrations.
Some guys report none.
Some guys a little and don't care. Mostly guys who actually wheel their vehicles.
The DD guys seem to say that more.
But then again......
