Looks like exhaust gasket leaking. Replace gasket.

Nope. Either you have a warped flange and a gasket leaking because of it or you just have a plain old blown out gasket. Sorry to disappoint you. Once you get the leak figured out then correct you're jetting.

Header flange isn't flat...
My first attempt looked like that.
Ground it flat, checked with a flat edge.. Good after that.

Can i keep riding like that?

Yaaaa...... but since you dont have a brace to the exhaust anyways, why not fix that and add a brace to the frame so that doesnt potentially break exhaust studs and give you more problems.

Its a really simple fix...

That exhaust looks kinda heavy, which will pull down & cause a leak exactly where the black mark is; as advised, replace the gasket & brace the exhaust to prevent a recurrence...
