 Someone told me to do it with a chisel and hammer on the corner of the nut
but when I tried  was just going to ruin the thing. You need a big spanner
the correct size - I bought one for about 20GBP- its a magnificent beast and
weighs a ton!, and a long extension and maybe the heat. Its a lot easier to
do with the exhaust fitted to the engine but out of the car- the apron gets
in the way otherwise, but I think its possible in the car with a bit of
contortion. I tried off the engine but I couldn't hold the exhaust tight
enough to get enough purchase. When I did it last I bought some of the
copper oval gaskets for a bus exhaust and rounded them in a vice, and then
softened them by heating red hot- they turn out the right size for sealing
in that joint!

Good luck,
