the one you say that looks snapped of isn't, on the chassis there is a mounting for an exhuast bracket which isn't used.....not sure on the cabriolet.
The scorpion exhuast didn't have the bracket fitted, someone else i know had to have a bracket fitted in the same place i had to have mine done, get yourself upto BELL exhuast centre 30 min job they will fit another bracket on exhuast/chassis, remove all underseal and fit the rubber for £40.
