Genset exhaust (venturi/genturi)

[mbulriss]

From a tip on Vintage Birds, long before I ever saw the Gen-turi, most
of us just went to any muffler shop for about $40-50 and got a couple
lengths of exhaust pipe and a hanger. Have them flare the pipes to
join them together and put a 90 degree bend in the one that fits over
the genset exhaust so that the upright portion sits out about 8-12
inches from the side of the Bird, as you prefer. Slide the lower
section on the genset exhaust, insert the second length, rotate it
upward and hook it to the roof top goat rail with an exhaust hanger
bent to fit. To prevent the bottom section from vibrating off the
genset exhaust, drill a hole through the lower section where it slips
over the genset exhaust and slip a 1/4 inch bolt through them both at
the genset outlet rather than take the time to attach muffler clamps
on the bottom one. Gravity and the muffler clamp takes care of the
upper piece staying put. I suppose if you worry about touching the
hot lower pipe, you could just get a second larger pipe to go over the
lower section and screw in metal screws or bolts to evenly center it
around the inner pipe and you'll have a fancy venturi one, although I
doubt there's any real venturi effect to cool the outer one - on a
hundred degree day, it's still gonna be a hot piece of metal, ask any
Texan that has sat on anything metal in the middle of summer - just
once. Geez, to think whoever posted that free tip on vintage Birds
could have patented it and given it a fancy name like Gen-turi and
made a bunch of money!
