Hi Tony,
Have dug out the exhaust and checked it over, the tailpipe is fine, the main silencer section has paint that has flaked off and very light surface rust, there are no perforations to the metal itself, I've not found any blistering and I've checked the weld around the points where the pipes meet the silencer. The curved section that joins the centre box has a wee bit of surface rust in a couple of places but I've given it a thump with a big screwdriver to see if the metal is weak and I cannot find any iffy spots. I have photographed the end so that you can check the fitment as it is not the slide over sleeve fit, (not sure what this fitment is called - someone enlighten me?) Swivel / Ball fit ?
A good going over with a wire brush and a lick of paint and I reckon it'd do the job nicely.
I'll drop you a PM
