Well I had to re-site the extra rear mount that Charlie fitted after about 400 miles. When the exhaust got hot it moved back, but the rear mount Charlie fitted was causing the exhaust to buckle a little and thus the tail pipe touched the surround and melted it. So add £18 for another surround (I can see it's done similar on yours btw ;-) )
The centrer section split on the welds at the front and rear of the rear silencer. Had to have it re-welded. This was possibly due to a design fault or a couple of parts had been missed. Can't remember how long this was, but I posted a thread on here about it. Was within 12 months.
And as for the only one... Ask Timclio172 about his... lol.
