Craig, thanks for the update. The upgraded mufflers don't look all that different to me...maybe a thicker weld bead along that 90* section to "build up" the deflection area, but I don't see much else.
The fact that you are still experiencing that fluttering noise at/below 2,000rpm on d-cel, WITH THE REDUCTION CONE, concerns me greatly. Not from a performance standpoint, but just that this fluttering is a frustrating aspect that
shouldn't be there.
I would suspect that the 2.5" ID are considerably quieter than the baseball-esque 3".
