Rattling noise in engine bay

[Lerm]

So I bought a 2014 xr6 turbo a month ago and for a while I had a rattling noise from the engine bay on idle and have just realised it also rattles when at low rpm (cant hear much at mid-high rpm due to the exhaust). I can really only hear the rattling noise when sitting in the drivers seat with the window down, I just had the idler pulley, pulley tensioner and drive belt replaced because I thought that was the issue but its still there. Any help would be appreciated as it doesn't sound good at all.

 

Mods (all done by previous owner):

1000cc injectors

3.5inch turbo back exhaust with 4 inch cat and mid muffler delete

fuel pump (unsure what fuel pump)

1000hp rated intercooler

battery relocation/turbo side intake

braided turbo oil line

NPC twin plate clutch 1000hp rated

tuned to 327rwkw

Auto or manual? Could be flex plate if auto.

Its a manual forgot to add that to the post.

it says "NPC twin plate clutch" ... it's a manual...

 

that being said, all twin plate clutches rattle around a bit when they're in neutral...

 

Does it happen when you're sitting still and changing the revs? or does it only happen when you're rolling/driving?

[Lerm]

It happens when sitting in neutral and taking off from what I can hear, the exhaust is too loud for me to hear if it happens while driving.

Clutch thrust bearing? Or spigot bearing perhaps?

Could it be one of those things if the sound happens when the clutch is engaged and disengaged?
