I'm interpreting "upgraded" as meaning a redesigned, aftermarket part which has now proven unreliable on two occasions. In contrast, my original 21 years old straight pipe lives on. Hmmm, interesting isn't it.
I can't help thinking that the problem lies with the aftermarket part rather than due to any other factor.
When mine first leaked I reached the same conclusion as you have. The welded seam was covered in antifreeze residue. However, I removed the housing and filled it with water and could find no leak so I refitted it.  I did fit a new 'O' ring though and guess what? The leak was cured. I then realised that the high pressure coolant was probably spraying upwards from the 'O' ring and depositing itself upon the widest part of the housing which happens to be the seam, thus completing the illusion.
If you can get hold of a genuine MG Rover straight pipe, try fitting that in place of your Rimmer Bros. "upgraded" item.

Hi Simon, the pipe I was supplied with to replace the failed one in the kit was a PEP101970.
The original kit was a PEM101050K, which I believed to be a genuine item rather than an aftermarket one, which included a temperature sender which I had been advised was a contributing factor in a cold starting issue the car had been suffering with.
When comparing the plastic parts at the time, the ones which I had removed had a smooth texture to the curved pipe, the straight and the housing.
The replacement parts had a slight texture to the finish on the pipework, but not the housing itself.
