Mine's 60mm OD Dave. I measured it this morning, with vernier calipers!

How Strange. I purchased a 190 exhaust complete even though I just needed the back box. When cutting the original one piece exhaust pipe to receive the back box it was 3mm too small

Now you tell me 'Exhaust'!
The Missus was thinking I was in the bedroom measuring up for a pump!

I bet you cut it near the bend. Pipe bending rigs cause a reduction in OD for several inches either side of the bends. The unswaged straight part is 60mm. A 1.8T back box (new on the shelf here) has 60mm OD straight section and 57mm OD near the bend (vernier gauge).
