At this point I would not rule out a loose heat shield, panel, or something. Also I had a muffler with a bad resonator inside, whatever its called INSIDE the muffler come loose and cause exactly what you are describing.
A thorough underside exam hitting parts is first step.
Also, is the vibration/noise you hear RPM related or speed related?

Welcome to the forum evomind!
It is a pleasure to find a first-time poster offering advice to someone else, rather than the usual questions of "Why is my Boxster now a smoking heap on the side of the road? Will it be expensive to fix?"
I suspect you are right, I really must diagnose this one properly. I've spent far too much time and money guessing and replacing with no positive results.
Hope to see you around the boards.
