Dixis or Gruppe M backbox????

Been measured at 98db at Donington, but will ship with a special extension to bring it down to 95db. I won't deny it's been made for performance and noise so it ain't quiet

my SS race b/box is 96-98 static so must surely be driveby

My SS race back box + SS un-resonated centre section was 100dB at Spa.

I was usually 97dB like Shim without the SS centre section.

Static

Although weirdly enough the old race system tested today at Castle Combe at 103db, went out, got it hot and down to 100db, track measurement is hardly a science.

I could probably do a custom 200 cell race cat full exhaust with centre exit for £750 fitted. Only problem is as I say noise. Ill do some work on it, and try to get carbon made for the diffuser.

It would be considerably lighter, ill work on it over the summer.

How many boxes did it have John, to get it to 97 static.
