Does anyone recognize this part? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I found this tube in the back of a 75-ish K-5 blazer in a junkyard. I was thinking it was a stove pipe for the heat riser system for 67-72. But after looking at it, it looks similar but not the same. There is a little cup on the bottom that the tube slips into. I just didn’t take it apart when I took the picture.

Anyone have any idea what it is?

4x4 upper radiator hose for later models?

I don’t think that’s it but could be wrong. It’s necked down on the bottom and belled out at the top. Like something slips into the top and it fits into something on bottom.

I think it's a heat riser tube.

Bingo! they usually get tossed with a header install

Heat riser - part of the air cleaner system. Might have value, since they get tossed often?

I see a short cut piece of what looks like exhaust system tubing also in one of the pics.
