Exhaust header torque value

Anyone know the torque value for the exhaust nuts? I don't see it listed in the service manual... Is it shown here as "exhaust pipe holder studs"? ...with no value listed?
Looked online and have found everything from 13 ft/lbs to 69 ft/lbs...
I know it's not a critical value, and many just say "tighten the shit out of it"...but I'd rather not over-tighten and snap off a stud.

Thanks!

The reason theres no torque setting given is because there is a crush washer in there.
Now looking through the B service manual, there is also a crush washer when attaching the standard exhaust can, and the torque setting for those bolts is 34Nm.

Do each a bit at a time and see what feels comfortable.

For Tech Questions Bike Model letters and Country are more useful than saying the year, for UK owners anyway, as registration year is not always the year of manufacturer model.

Just hand tight with a standard 3/8" ratchet. Don't use a breaker bar, don't torque it, just tighten it.

Use copper spray to make it stick and a long reach lighter. A breaker bar, without a 6ft cheater pipe attached is just another breaker bar.

Thanks guys...
Can anyone post pics matching this one just so I can compare gaps? THANKS!

I did replace the crush washer and using a 3/8 torque wrench, with a 10" extension and a swivel socket. The setting on the wrench is 20ftlb - but I know this is affected (lessened) by the extension and swivel. (for comparison, 20ftlb is the same torque used to secure the brake rotors to the wheels)
