To Sports Cat or Oem Cat?

I am in a similar situation.

Would a 150 cell sport cat pass the NCT on a Twinscroll. ( Have it ready to install ).

Previously had a Milltek Sports cat on wrx and never had any issues, once warm.
 
From what I read, 100 cel won't. 200 cel will pass...but I haven't a clue about the 150.
Was the miltek 200?
 
I always heard 200 and up cell passes ..

Suppose one way to find out u have the factory cats as well mark?

Mine will only pass with standard cat in and one in centre section so hard to know it's a bit of a lottery
