Did you try tig brazing? I would like to think that would stick fine(?). Or is that what SiBr is?

Yes. That is Tig braze.

Do you think it might be the plating that’s making things difficult and not the metal itself? Maybe could try blasting it, glass bead or aluminum oxide, etc.

It’s more of a discoloration than a plating. Silver solder flux turns it bright silver instantly. Any grit sandpaper will shine it up also. And then heat turns it back yellow

It helps to sand it off first. Filler won’t flow at all if coating isn’t removed.

Expected these to be yellow. New 500i muffler covers straight from Stihl. I will find out if they are yellow after some heat

This is my 395 I picked up that took a hit and broke a piece of the case and dented the muffler so it was a good place for a deflector and I smooth ground the jagged edge on the case .
I have to find some touch up paint for it and possibly gonna weld the deflector on the muffler on the future.

Way to make a software bug into a feature. Looks like it was modified on purpose.

Alright finally figured out a deflector to keep the exhaust off clutch cover on my 400. Took some stainless sheet and cut out a little pattern and bent me the shape I wanted. Then tigged it up. Now these welds weren’t pretty. I’m not accustomed to welding stainless this thin. But I turned the amps down to 30 and ran a sharp tungsten. Polished the stain off the muffler and started tacking. Holding more to the muffler and running filler to the deflector and following back to the muffler. Really had to keep moving and still had a couple problems but at least it turned out so here she is ugly welds and all. (The first two pictures are to show the opened up factory outlet and how I ground out the factory deflector.)

And of course on the saw.

Old school 372xp double jungle muffler with a @tree monkey deflector kicker for a little extra pop.

Allow me to introduce the BCS (Bogie's Custom Saws) woofbox... not too shabby for mild steel and a flux core welder....dang 16ga is difficult to lay a consistent bead on with 030 flux core LOL

372, simple but effective.

Quick 'n' dirty Dremel mods on a Hyway 066 muffler. I followed Stump Shot's advice on leaving the baffle walls and just topping it, way easier than drilling out all the welds.

Just be sure to match/bevel the entry from the exhaust port so it's not hitting a square edge sticking into the port and your gasket too.

That will be done when I get the 056 Mag II jug securely mated to the 066 case and I get the mounting adapter between this miffler and that jug figured out.

Looks better with some paint. I haven't seen this high heat paint before so I thought I'd give it a try.

That's the paint I use. It's not resistant to solvents until it gets a few good heat cycles.
