2010 xc60 T6 exhaust noise disappears after warm up

[GoLuckydog]

All,
I have a 2010 XC60 T6 AWD that started making a leaking exhaust sound by drivers side front that disappears after the car warms up. This to me would be similar to an exhaust manifold gasket or bolt breaking. I havent gone underneath yet but, is there an issue that is along these lines? To me it seems as though when the metal heats up it "seals" the gap. Does the flex hose off the manifold or the flange make this sound as well?
I am trying to get ideas of where to look when I am underneath tomorrow.

Thanks

hi, i know this several years but was interested if you found the root issue. I am having the same issue.
