2017 Ninja 650

I know im not going crazy because my buddy rode it and said he heard it too. Sounds of metallic rattling near front of the bike. we took about 30 minutes and couldn't find anything loose that would cause the sound. Anyone got any ideas or have heard it before? Here is a video. I know im im a high gear but I only hear it in second and third, cant tell in first gear.

Only really modifications are the exhaust which is just some ebay pipes and a akraprovic slip on.

I was going to get a tune for it next week but im concerned now.
