Nice one Harry
As it happens I'm looking to get a noisy system for my Aero 1.
I currently have the Librands rear exit which is far too quiet. I want full on muscle car racket so I guess the side boxes need to be a fraction of the size they currently are but I still want rear exit.
Can you tell me what you ended up with in terms of configuration and what the total cost was.......You may have detailed this in your post but I can't read.

What series is your car.....can't keep up with all the swapping around on here
