Fitted it with the original inner sleeve as recommended on here , seems to be about 1mm to small each side where as the supplied sleeve sits about 1mm proud each side , so don't know if that's got anything to do with it
The vibration when stationery is creating a rattle , which wasn't there before , the last time I had a rattle like that it was the flexi joint that had split , causing the exhaust to move and rattle so will check that tomorrow.
