I'm not sure if this is related to you guys, but there was a SIB for the vibration in the cabin because of a certain frequency with the convertibles 55-65 MPH - it causes a resonating frequency that vibrates within the cabin and car ONLY from 55-65 mph. probably not a cause, but thought you might like to know.

Did you have any of this prior to having the exhausts installed?
