Remove a broken bolt using a left handed drill bit
Removing a broken bolt or stud can be extremely difficult but in some cases such as when the bolt head has been sheared off by sideways force it is possible ...

I don’t think that vid will work for me considering it’s not broke off all the way in it’s still able to have something circular to grip it and twist it off I tried a 13 socket it but it won’t grip it like it should since it’s circularRemove a broken bolt using a left handed drill bit

PB BLASTER & PIPE WRENCH?
You may end up breaking the bolt further down, then you can
drill it out.

There's a tool that will grip that stud like a pipe wrench, forget what it's called, round tool that you turn with a socket. Key to remove that stud is heating the surrounding area on the manifold and if there's room use a pair of channelocks on stud.

The manifold is still attached to the motor in the vehicle ? At a minimum it's gonna take a torch to turn that flange red hot. If you don't have a torch, take it to a muffler shop and they'll get it out. If it's bad enough they may say replace the manifold.

There are several ways you can use to remove the stud. The firts thing you need to do is apply pentrating oil and let it sits for a couple of day while applying more enetrant which will help break some of the rust; you can tap it some to help pentration. Now you can use the double nut technique to extract the stud with wrenches; if you are liucky the stud will come out easily. You can also apply heat with a torch to losen it further. Some prefer to weld the nut to the stud and use a socket. Some people recommned using an impact wrench to loosen the stud, others claim that an impact will break the stud. If it breaks, grind it even with the manifold and then use an extractor.
