Hi all away for the past two weeks and when I came home I noticed a slight rattle in the rear of the car. Got it up on a ramp today and the two rear exhaust clamps are corroded, problem is you cannot buy the inside clamp so I have to replace the exhaust from the cats back and a new box even though there is nothing wrong with it!! Expensive exercise too!! Anyone know a way around this? Get a clamp manufactured etc? Potential bill of €1700 the clamp I'm referring to goes right beside part 18 in the diagram? Any help appreciated
