"Snap"

Apologies I couldn't resist it
Sorry to hear that, did you have the sport / loud exhausts fitted? I've had two snap both on the left side, apparently the steel is .5mm thinner than the standard ones.
The dealer has refitted the original exhausts and I'm waiting for MMC to sort out the issue with the thinner pipes.
First time it happened only a few miles from home and I managed to limp the car home with a few chips to the paint work. Second time the wife and I were about 80 miles from home but this time I was prepared for it with tape for the side of the car and wire to support the broken pipe.
We had to go through the Dartford tunnel on the way home, slightly noisy
