I have never seen a header quite like this one. I certainly remember Dunstall from their bodykits and fairings back in the day and their honeycomb baffles.
Anybody seen one of these?
Any thoughts about the scavenging qualities of a set-up like this one?

these are just HEADERS there are suppose to be 4 tail pipes which the guy does not have . look at the end of the headers and you can see the clamps that attach to the muffler pipes . it will look like the original pipes on the old Z1 if it is complete ( which this one is not)

Yeah fee, i saw they were just the headers. The clamps actually are for the head pipes to connect to the collector.
According to the picture on the box they will empty into two upswept mufflers.
Apologies for posting in the wrong spot.

You've got the system backwards. The 4 clamps clamp down on the 4 headpipes shown, it's a 4 into 2 system like stock. In my view no better than a stock exhaust, exhaust cannot easily exchange from pipe to pipe as in a good 4 to 1 header collector. In some ways it has to go backwards, pressure wave tuning destroyed somewhat with that setup.

Yeah, I made up a set like this for a SOHC 750/4 F1 at one time, sucked in a by a theory that it would work better than standard. It didn't, but the system was lighter than the stock 4-1 and huge muffler.

Oh, it'll work fine on a stocker, just don't go looking for big horsepower increase.
