I went out to the garage and noticed a pile of yellow dust/ powder under the cruiser. I crawled under and saw the same yellow powder in spots on the muffler. I’ve never seen this before and google turns up nothing helpful. Any ideas?

Just for giggles, scoop some up on a sliver of wood and see if it burns, it sure looks like sulfur.
I have no idea why sulfur would be on the muffler unless it was in water you drove through and it was left behind when the water evaporated off.
Been driving through any orchards recently, or visiting the hot springs in northwestern Ga.

It does look like sulfur but it does not burn. It has no scent and no feelings of euphoria when ingested
. I did go wheeling in N Georgia last weekend but when I got home I pressure washed the under carriage to get the GA clay off before I parked in the garage. I’ve gone to that area lots of times without having this happen.
Right - that looks like classic electrolysis corrosion to me (but I'm not pro) - almost like battery terminal corrosion on the frame. Crazy stuff. You need a zink anode on your truck - ha! Salt water?

My thorough Google research confirms this as yellow finishing powder, aka banana powder. Clearly your rig has been getting all prettied up for the bright lights of stardom.

My rig doesn’t need that non sense. She has a raw and natural beauty that radiates like the light of 10,000 stars.
That is so weird. This is just a guess..... Iron lll oxide has a yellow color to it. Iron lll oxide is also the most soluble of all the iron oxides. Because it is the most soluble, Iron lll ozxide can get concentrated by water flowing over a rusty area where it picks up more iron lll oxide than any other type of iron oxide. This could possibly explain what you are seeing if water full of Iron lll oxide was dripping on a hot muffler maybe it could precipitate out in a pure enough condition to look that yellow. Again this is just a guess, I also think it could possibly be some kind of a sulfate mineral or even calcite mineral because a lot of those can also be yellow.
Could it be sulfur due to burning high sulfur gasoline?
The yellow powder is Hexavalent Chromium Cr(VI) that is the most toxic form of chromium. Do not touch or inhale it. Wear protective equipment including gloves, respirator mask and goggles when you observe this powder and treat it as highly toxic.
