Reply to "GTS exhaust gutting"

The exhausts I modified in this post now emit 112dB at 3000 RPM. My friend recently had it tested at Goodwood circuit.
A few years ago I had my car tested (with the factory group 3 exhausts) and found it to be exactly the same 112dB. So it would seem having all the holes in the Y piece makes no difference to the volume at all. I certainly wouldn't want it any quieter.
