https://vocaroo.com/i/s1YLlF0CaS3C

Rattling noise from/under engine bay driver side, only appear driving above 80kmh, will disappears after reduce speed.

Not alternator belt, not belt tensioner, not alternator pulley problem.

Heat shield?
 
Is it a metallic sound?On my Lancer I had a loose heat shield between the header and catalytic converter. It would rattle between certain rpms and drove me crazy.
