Is this a Catback Exhuast?

Hello all,

Just wanted to clarify something on the following Exhaust.


Though the Eisenmann Quad isn't advertised as a Cat Back exhaust, the actual parts seem to suggest it is. It is described as "Complete with connecting pipe, Intermediate Silencer"
http://www.eisenmann-sportauspuff.de...26900764_2.php
From the other forum, after installing the exhaust the following was removed from the car:



The image looks to be removing what looks like a intermediate resonator or a secondary cat box. I checked this on real OEM.




So, from the above, can I deduce that the 3.0i came a mid pipe silencer and not with secondary cats and that the Eisenmann will replace this with a resonator? OR is the Eisenmann "Silencer" another word for cats?

I thought all modern cars came with two sets of cats.

Picture of the system of which looks Identical to the 35i.



Picture of system under the car.



Thanks very much for the help! Hope it was clear.

Cats are in the down pipes not the exhaust AFAIK
