There Klock Werks and I haven't been able to find anything from them.
Probably best to give them a call. I can't find anything either.
Couple things you can do though. Go to a hardware store and purchase nuts that have the anti-rotation crown on them, or you can use the nuts you have now and stick a flathead screwdriver between the nut and the housing so they won't rotate while you're tightening them.
Simple solution: push a flat blade screwdriver along side the head of the bolt (or nut, what ever is inside the slot on the muffler) to keep it from spinning. Works every time.
I keep small wooden wedges just for that.
You can wedge a screw driver sideways to hold it that way you shouldn't have to hold it.
Are your sure the thread isn't damaged?
If it's that hard to tighten something may be wrong. You can use a stove bolt if need be. Just get the right size.

Can't believe no one has suggested speed nuts. They are narrow U shaped gadgets that slip over the bracket that the bolt goes through. One side of the U has a hole bigger than the bolt and the other side has a threaded section for the bolt to screw into. The bottom of the U keeps the speed nut from rotating. They are available at hardware stores, home improvement stores and auto parts places, Oreilly's, Autozone etc. Take in the bolt you want to use so you can match size and thread pitch.
Obviously, the best solution is the factory hardware if they are supposed to include it with the pipes.
