These things have a header that comes off of the engine, then goes

I'm thinking that I can fabricate one of these with a machined
header,
machined ends, and a section of tube. But it'll all be aluminum, so
how
to join the pieces?

Could you use machine screws to hold the header to the front machined
end? And then run a threaded rod through the tube to hold the
machined ends.

Or use lost wax casting to make it as one piece.

That could be cast with a simple core . For that matter , if it's one that
has the inlet port at 90° to the main muffler , cast it as a solid , machine
the interior , cap the front with a threaded dome . Built an R/C boat once
upon a time . While I was saving up for the radio gear it "got broke" . Long
story ...

You would have to suggest that. And here I have a Vibration & Stratton
engine that's just crying out to be broken into bits and recycled as all
sorts of nifty stuff.

Do you need to implement control loops in software?
"Applied Control Theory for Embedded Systems" was written for you.
