Still questions about 200 cell catalysts

[Buzzi77]

Hello, I bought the 200 cell catalytic converters for aston Martin Vantage V8 of 2006 4.3 . I mounted them and I must say that the noise is very nice, maybe a little too much for me in the city.
Now I kindly ask you:
1.)
If I buy the Velocity ap ecu modification from DAE, does the noise stabilize and become less loud?
2.)
Do you think that by refitting the fuse 22 I could travel around the city in a more discreet way.?

Thank you for your kind feedback.
🙏🙏🙏
Ale

I don't see how a tune will make it less noisy

By refitting fuse 22 it will become quieter between 1500 and 3500rpm (although I understand that the second rpm value can be changed with a remap)

To make it quieter when you choose, you need to fit a 3 way exhaust valve switch.

Why did you not simply have your existing cats adapted, to make them 400 cell, together with a 3 way switch?
It is the modest cost solution for your period car and you would not have needed to ask your present question.

I don’t think mine are loud enough lol Refitting the fuse will help for ‘normal’ driving and as said an exhaust controller (CCCharger) would give you total control, open and close from a remote.

Please explain how the remote exhaust valve controller can keep the exhaust valves closed all the time.
Mine cannot do that.
