My Ride: 2004 330i ZHP
There is no rear cat, there is a silencer/resonator just below the headers. The cats are in the headers themselves, there are total of 2, one for each group of 3 cylinders.
This is the layout of the cats:

1984 318i - Dead
1998 328is - Sold
2004 330i ZHP - I think I'm in love
