BMW R18 First Edition 2021
When washing my bike today, I discovered one of my exhaust pipes was loose. I removed the 2 bolts, readjusted, and tightened it back up but it is still loose. Any assistance is appreciated.

Missing copper gasket between header-pipe and cylinder head?
I have the thin gasket. some of the legs on it were bent. I am going to straighten the fasteners up and try again. May need a new gasket.

Made a temporary shim to get me through today. New gasket on the way.
 
JayB: Do you hopefully know the factory torque value for the header pipe bolts? Thanks
