Sounds like the engine makes that sound through the entire video.... My first thought:
- How many miles are on it?

Followed with, it runs fine, just has that noise, try the remedy that worked on my wife's 3100 Grand Am, throw in a bottle of motor honey or Rislone. See if that changes things after a day of driving.

The noise does quiet up alot once the engine is warm. Mileage is roughly 143k and yes i still have to try a bottle of motor honey and see what happens.

You didn't let it get up to operating temp!

But yeah the guy in the first vid is full of it, lifter tick is normal not piston slap,

Yours sounds more like piston slap, if you let it warm up everytime you drive it it should last some time

When we where looking for a car I want to test drive a 5th gen the chick tried to give me the line it ticks but the mechanic I brought it to says it's normal, when we got there to test drive it she was running to the store in it, took it for a test drive and the piston slap was so bad when you would stick it in first, bring the RPM's and let off ( engine braking) you could hear it slapping

Just keep your maintenance up on it, I'm sure a new shortblock is dirt cheap for that engine anyways.
