Any tips getting the Y piece clamps off?

[RumbleBee]

Im changing the exhaust manifold gaskets and Im going to remove the pre-cats and repair that dripping power steering union at the same time. Got the exhaust off and disconnected the Llambda sensors but I can get the bloody clamps off. Am I missing something? The clamps attacht he manifolds to the Y piece. I have removed the M6 aerotight nuts and levered until Im blue in the face. Anyone got any tips that might help. Its a 96 Chim 400.

Thanks in anticipation.

If it's stuck, use a drift and gently tap the exposed end of the clamp tangentially, as if you were trying to turn the clamp around the exhaust (iyswim) so that it pushes the two ends of the clamp apart.

Will try that.

Thanks very much.
