Looks like there are broken studs in the threads.
Had the same problem on mine. Only way to get this fixed is to drill them out and recut the threads.

There are no threads visible, only the hole which has no exit gap has thread. Can't these things be mounted with a simple bolt/nut trough it (because it are drilled out holes now)?

I´m not sure if I understand you correct. You had some broken bolts in the threads. You drilled them out. So there is no thread any more.
If thats the case, it´s not a very clean solution because there is no flat surface on the back of the exhaust flange. A nut will nut lay flat and straigt. But it is possible.
Except the hole that has no exit. there you can´t use a nut.
Best way in that case is to cut a oversized thread in all 4 holes and simply use stronger bolts to hold the exhaust. Just my opinion.
But you want to sell them here, not any repair advice.
