XI muffler options...what's out there??

I've searched and XI's seem to be the red headed step-child for aftermarket mufflers. I would like to find a "performance" muffler, not cat-back system, that would make a lower exhaust note, no annoying cabin drone at cruise and fit the XI. I found products by Dinan and Supersprint that seem interesting but may be too open where they pop and sputter on throttle release. I don't expect any actual performance gains and am not interested in resonator deletes, headers or fart-can solutions, just a subtle, lower note.

What do you XI owners recommend? There is a BMW performance muffler spoken about but I can't find 'em. Anyone run the Dinan or Supersprint muffler only? I'd like to know your results.
