Just to update the forum, I got a friend of mine to cut and weld the new pipe to match the original, and weld the end back on to the original pipe I had to cut to remove from the car, which had only surface rust on examination. The replacement pipe needs some slight adjustment so the original has been used until the engine is run in. I now have another pipe that will need the same treatment and a possible place to have it bent.

Looking back over the thread I notice in my July 24 (3.51) posting I borrowed an 'i' from Ruairidh's name to use elsewhere and forgot to say - sorry Ruairidh!
