I would take the cam cover off and check cam belt/tensioners. My old man phoned me and said his MV6 was making a tappety noise, turned out the tensioner was in melt down :o

Exhaust gasket leak can sound remarkably like this.

Normally an exhaust manifold leak starts off noisy and gets quieter not the other way around.

Agreed, sounds like a loud ticking which is engine RPM dependant & gets quieter as the engine warms up eventually stopping completely
