Muffler's Falling Off

Hi Captain, the hole in the exhaust uses a pressed nut (Similar to a rivet with internal thread) to attach too. Yours has pulled out.
If you know someone with a press nut tool, you can refit and reattach with a new bolt.
Alternative, although not beautiful, is revit a bracket on with sealer to cover the hole and bolt to existing bracket OR
Replace with new, although they must still dampen or you would have thought of that option.
Best of luck mate

 

It could be welded back on but it wouldn’t be pretty

 

A rivnut is the obvious answer but even in Oz I suspect that corrosion may have eroded and weakened the surrounding material such that a rivnut would not hold. If that is the case then apply a little lateral thinking.....
Fixings for plasterboard/drywall like this could just give you a cheap, simple solution- a cavity wall anchor.

 

Capt
You can also get those inserts if you search. I have done it before and when inserting them I used superglue in the recesses then tighten them to expand them a little and they should hold.

It’s too much weight for a rivnut. That must have been from someone’s modification as a silencer weights an awful lot and doesn’t have the structural mounting areas like for example a household shelf ie one at either end so the stresses are all overhung and want to be welded back at some point note. That’s why you lost it in the first place.

 

If the riv-nuts doesn’t hold get someone who can braze to reattach the bracket but you’ll have to get the bracket and the repair area clean.

 

What about just using an exhaust strap.
