Default weird metallic rattle noise from engine under load

1995 impreza with EJ20G swap.. so ive been getting this weird noise under load.. starts happening just before getting into boost. it sounds like a metallic rattling/flapping sound, kind of like an exhaust leak would sound. at first i thought it was just that, so i changed out all the exhast gaskets. I thought maybe the uppipe was cracked, cause it seemed to move a little. so i sent off the manifold to grimmspeed to pnp and ordered their uppipe as well. so even after all that the noise is still there. I checked the intake piping, and its all good, no cracks or leaks. its got me stumped
