Fitting new Y piece.

[fog66]

Hi, I'm going to be fitting one of Clive F's Y pieces and the instructions say it can be swapped without dropping the exhaust, just undoing the clamp from underneath and the V clamps at the manifold and then with a wiggke and pull, voila. My question is does this translate to peoples actual experience of removing the Y piece? I'd prefer not to remove the whole exhaust if necessary.

Any other tips gratefully received, many thanks.
