Loud Valves or Exhaust Leak?

It's from the passenger side. I'm not a giraffe and don't have a tube to listen around, but tried to capture it from my phone. The driver side noise sounds like every other 4runner; passenger side is much louder. It is not throwing any code and it drives perfectly fine, just loud. Anyone has any idea what this is?

Hard to say from just a video, use a broom handle, stick or very long screwdriver for a makeshift "mechanic's stethoscope", press your ear against the the side of it with your hand cupped over your ear, touch the other end along the length of the valve cover and then along the exhaust manifold where it attaches to the head, you should be able the determine where the noise is the loudest and if it's on the valve cover it most likely a valve tick, if on the exhaust manifold more likely an exhaust leak.

You can find a real mechanic's stethoscope at most auto parts stores for around $10+/-

Sounds like mine before I replaced that exhaust manifold on that same side. I proved it was that on mine by putting a few pounds of air pressure into my tailpipe with an air hose. I could hear and feel it leaking out where the manifold attaches to the engine. Most exhaust leaks that are before the muffler will also give a popping noise when the throttle is blipped.
