The frequent heating and cooling may put stress on the gasket and eventually cause cracks that may lead to exhaust manifold leaks. At a cold start, these sounds are seems to be more pronounced or loudest because in cold temperature the gasket heats up more frequently, expands and seal the leaks in a most efficient way.
