Metallic rattle driving me insane

Hi I own a Mazda CX-9 2017 2.5 turbo with 240000km. I have a metallic rattle that’s gets worse under load between 2000-3000 rpm. Coasting is fine. It seems more on the passenger side. That’s the left seat in Australia.

The Turbo is fine. The inner and outer exhaust manifolds have been changed and the rattle is still present. Exhaust shield is fine.

Does anyone have any ideas what could be it’s driving me insane. Thank you 🙏
