Catchcan/valvecover

[NorwegianMK5]

Hello, I ordered the «PERFORMANCE KIT FOR 2.0 TFSI EA113 ENGINES» from rtmg performance, which includes a billet alu valve cover and a catch can.

I was wondering where the catch can itself goes as the place where everyone is putting theirs (behind right headlight) has a large black box which is twice the sice of the catchcan.

Any idea what this is or how to delete it if needed?
