My cats have been rattling for years. You can’t hear them from inside the car, so it doesn’t bother me. My previous S8 (now with David’S8) had aftermarket sports cats fitted and I know there have been some minor issues with the O2 sensors triggering the engine management light occasionally. I think (??) this can be resolved if some sort of spacer is fitted between the exhaust and the sensor. David is in France just now, so he might not reply quickly.
