 Your setup looks insane!
I have Velocity AP decats installed on my Aston.  They replace the passive CATs that are not monitored.  I am retaining the factory exhaust.  I wanted to preserve the factory sound, but get more power and more sound.
Fabspeed also makes parts for Aston, but Velocity AP is more popular among Aston owners.  I think each marque has the preferred vendor even though multiple brands are available.  Fabspeed seems more popular with Italian marques, especially Maserati.
