What did you weld it with?

Hobart 210, .030 cuz I'm lazy and didn't want to change wire

Sometimes it works well, and easily, sometimes not.
Actually sounds like a big Husky now

Looks good! I can’t take credit for the mod though. I think it was @Mastermind who posted about the 395 mufflers a few years ago.

We cut a hole in the top....then pull the guts out that way.

That makes sense as all the braising is to the roof of the thing.
Next one, I’ll know

What is the diameter pipe is it? Looks like stainless to me? I like the thin wall, I have issues finding thin wall.

I use 1” emt conduit and cut the OD down in the lathe….dirt cheap. Here is one of them before brazing & paint.

Fine work my friend. Smooth cut on the muffler as well!

Husky 359 muff mods…
So, what are folks doing with these? Looking inside there is all sorts of baffles, a pipe and God knows what else. I’m tempted to cut it in half, gut and re-weld but if the bolt tubes are well braised at both ends it may not com apart.
Thoughts?
I have 2 to do.
Years ago I just added a side port and called it good

Where do you get the tube? Stainless?

I get it at Menards…no, emt is just cheap galvanized conduit. Trying to braze galvanized is no good, so I machine it off and thin the wall a bit.

They kinda suck. I reach in through the inlet with a long burr and put as big of a window in the mid-baffle as I can
