Oh shite....

Aftermarket or stock exhaust? By the looks of the photo its the link pipe that has gone - if so I would guess it just needs to be replaced which is easy enough if its aftermarket as the cans are typically separate. If it's a stock exhaust then the whole can needs to be replaced as its sealed on to the link pipe I believe.

If on the other hand its snapped off from the downpipes then... I don't know. They aren't the cheapest things to replace unfortunately
