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!
