Exhaust Noise...popping during startup

It's really hard for me to hear the pop in the video. Your truck sounds good, like you have a modified exhaust. Maybe it's just the camera right at the exhaust.
Cold exhaust systems sound more raspy and pop and crack more than hot exhaust, it's also a richer mixture of fuel on cold starts. If you have a louder exhaust, this will be magnified.
I hate to even bring this up and worry you, but one of the few problems these motors have on occasion is valve problems. A bad valve can cause a popping/puffing sound in the exhaust. But from what I could hear, I don't THINK you have that problem.

Mine sounded like that. I had the front port on the passenger exhaust manifold gasket blow out. It would make noise when it was cold and then quite down as the manifold heated up and expanded. Changing the manifold and gasket took care of the problem. I probably didn't need to change the manifold, but the kit was only 75 bucks from rock auto so I figured it was cheap insurance. I had to lift the engine on the passenger side to get the manifold out, but no broken studs made life easier. Took about 4 hrs at home with no hoist.
