Act have a quiet system. I have it fitted to my car. It has silencing along the long centre pipes, the sports rear type silencing, plus extra silencing in the tailpipes. Its 106 db decanted on my car and I'm not missing any power (380bhp) and it's significantly lighter then the original back box, and has lots more road clearance.
They also have some additional silencers instead of cats to drop the volume further.
106db is really loud! I need to get mine quieter than than for trackdaysThey also have some additional silencers instead of cats to drop the volume further.
Mine is 106db decatted at 4500+ revs, or I've managed between 96 & 98db with the trackday cans on, depending on who's measuring. At normal driving it's quite refined.
If helps
I have in my garage back box for Cerbera speed 6 2003
I took it of some now four years ago
I fitted new sports box ( too loud if honest ) then sold the car
I would have no idea what's it worth but if you are interested , I can make available etc
I will check to see if I can find an ideal guide when it comes to it's value
If wanted just let me know

Is there much difference between the 4.2AJP8 backbox and the 4.0 SP6 backbox?
The pipes that connect to the intermediate pipes were about 150mm short and were closer together on the SP6 box that I put on my 4.2 I have just taken mine off to weld on some stainless sections to make it all fit properly after a few years with it bodged on with a couple of short lengths of mild steel pipe between the back box and intermediate pipes.
If you want to quieten your 4.2 for track days, I run a linked decat and standard (SP6) back box and have regularly passed 101dB noise tests at sprints. The noise measurement seem to vary from track to track and the marshals have told me that it measures variously between 95 and 100 dBA depending on which track it is!
