Is there something special about the bolt that it can't be replaced with a new one?
Or is it a stud? Or a threaded hole in a casting?
Need a bit more info I guess. ....

If you are bolting into a threaded hole (can't put a nut on the other side) and the threads are stripped, you switch to a bolt one or two sizes bigger. You drill out the hole (with the exact right size drill bit for tapping the new hole for the bigger bolt), and tap new threads into the hole. ....

Not sure I have the exact picture but there are new glues for holding bolts in concrete, and for locking bolts in metal, often an epoxy formula (you mix two parts together). Maybe a good quality one would hold for you. You'd clean and dry both sets of threads thoroughly, apply well, and keep from moving until it sets. Some epoxys set in minutes, others take hours, but I think slower is stronger. ....

It sounds like the easiest fix is a new muffler.
Assuming the 1830 is the same as my 2230, then the tapped holes are in the muffler; the screws go through a flange on the end of the manifold pipe and thread into the muffler.
I'm guessing that you took the screw out, and made sure it's not stripped and that the threads in the muffler are.
You could drill out the offending threaded hole in the muffler, and either tap it for a heli-coil insert, or tap it to the next larger size. If you go with a heli-coil, your old screw will still work and you won't have to drill out the hole in the flange. The next size up screw will require those things.
