KTR induction kit

Anybody got a photo of both cats I could have a look at so I know I think there's a silencer where the manifold comes down there's a square box where the decat fits can you remove that if so how??
 
There's the "pre-cat" after the flexi which acts as a collector and pressure equaliser from the manifold. I ran my F1 with and without it and on reflection I think the car is better mannered with it than without it. The sports cat and system are well worth it.
