Figured/hope there would be some professional welders on this site
My newest Cali came with Agostini mufflers and one of the shield mounting brackets was broken off. I haven't stick welded in years ( been using my MIG ) let alone welding Stainless! but anyway, I bought some 316L 3/32 rods to reweld the bracket back on., Would this be your choice?


Muffler bracket
 
Stick welding such thin brackets might not be my first choice . I'm a sucker for TIG welding thinner
material . But your Mig would be my second choice and stainless wire in a small roll is cheap enough.
And since the original weld bead is still there , a 'Bit' of grinding on the old weld and you should be good
to go . Have fun and show us your results . Peter
 
Hmm... I thought you had to use a different ( tri ) gas mix for migging Stainless. So I can use the same gas mix ( 80/20 ) with SS wire as I do with steel wire??

A shielding gas mixture that’s 98 percent argon and 2 percent carbon dioxide works in most cases for MIG welding stainless steel. A tri-mixture gas of 90 percent helium, 7.5 percent argon and 2.5 percent carbon dioxide is also generally ideal for welding.

If your 80/20 is Argon/CO2, that will work fine. If you want a “one-size-fits-all” option, a MIG welding shielding gas with a 75/25 mix of argon and CO2 is likely going to be your best bet.
 
Sorry busy cleaning up after hurricane Ian. Any way those rods will be good. I’d practice running beads on some same thickness steel. You only get on shot to do it right , I’d set my welder at 85 dc. If you had a TIG welder that would be better, but a stick can be converted but it’s slightly expensive.
