Considering the DOHC engine in the back of the shot I would guess they are for that

they do look like a '81cb650c's exhaust.

just played with one a few days ago, and it all looks identical as far as i can tell without viewing the pipes in person.

Just got a reply, they are off a 1982 cb650 nighthawk with a single overhead cam. It looks like the early nighthawks were singles.

if look in your clymer cb650 shop manual it has the 82 night hawk as sohc
looked it up exhaust is same only real dif is the 82 carbs have removable slow jets and the choke is a thumb switch, not a pull rod.
