Graeme, Can't visualise your exhaust from memory. Is your flexi-pipe the welded both ends type and if so is there enough room outside each end if it's removed to fit a clamp-on type. If so you can buy stainless clamp-on flexi couplings. If you ascertain the point of failure and loosen things up so you can move the exhaust around a little more you will be able to see that the, (usually upstream) pipe, enters the coupling for quite some distance so imagining the gap between the two pipes within the flexi, it is in fact quite small. This allows you to have a little more latitude in where you can fit the replacement. Remove the bellows part by cutting directly through the pipe that is the short end (outside of the flexi flange) then remove the other end close to the welded flange. I grind off the first high ridge and then you can slide the whole of the old flexi off. you can now see the extent of the pipe available and decide on the position for the clamped version. First tidy the exhaust flexi flange which sits on the longer section but do not try and remove it, it will just sit in front of the new flexi and in fact offers some protection.
When you have your pipe diameter you can order a clamp on version, easiest to search on line.
I fitted one on to my son's polo which had prematurely failed, that was five years ago and literally this week I have just changed his whole exhaust out for a full stainless option..... flexi on the old system was still fine!
