I notice Kunsmann also sell the CS centre silencer, which I would assume gives a little more noise.
I may have a look at this a little more closely. Does anyone know if it's a straight swap or is the bore different on the CS exhaust?
The CS exhaust has a smaller diameter after the centre box to the rear box> It is a stepped pipe so if fitting both it shouldn't be a problem. However i would only change for the CSS as this system has a larger bore from the centre to the rear box, probably only needed on the CSS but why not try it.
These are the CS exhaust system pics showings slightly smaller dia
