2016 GS F loud engine noise!

I am trying to pinpoint this loud noise coming from my engine. The vehicle has a little over 109K miles. Please help! Thanks

Sounds normal. The high pressure fuel pump and direct injectors are very noisy on this motor, but nothing sounds out of the ordinary.

Pre-buyer inspection concerns

Thanks for your response, I was worried because the tech who did my pre-buyer inspection said it was a lot louder than other GS Fs he has serviced. Is there anything else I should be looking for at 109K miles?
