Separating the Y-Piece....???
Discussion
Right, still on my mission to decat my Chim, just finished the 3rd day of battle and still only got 10 manifold bolts off - they really arent playing ball at all 
To take my mind off the irritating bolts, I started to take off the y-piece. So far I have unbolted the clamp at the bottom joining onto the downpipe and loosened off that joint, then removed the lambda sensors. This just leaves the clamps holding it to the manifolds. I have undone the bolt holding the clamp tight, then smacked it with a hammer to loosen off the tightening bit so now just left with the clamp its self which is clinging on the the pipes like nothing i've ever seen. Despite covering it with penetrative oil and smacking it with a big hammer, then trying to lever the clamp away from the pipe, it still remains unmoved... Not even a slight wobble! So does anyone have any great tequniques for removing it? Or have I perhaps missed something vital? Or do I just need to keep hitting it with a hammer and hoping for the best??
Also if anyone has any great ways of removing stubborn bolts, or wants to help this poor soul remove said bolts, please let me know!

Hi Nick, they take some jiggling about in a rotational manner to loosen the hold on the flanges, do be gentle with them when you do undo the bolt as i opened them right up on mine, stretched them and could'nt re use them, IF you do manage to find replacements (Had to go to a dealer for mine) they are about 30 quid a side!!!!
Hi,
I used a slim screw driver and tapped it in between clamp and manifold on both sides to lever it up of the flanges. I took my time and did not abuse it, when it did come off the Y piece and manifold sprang apart by about 3 mm so there is some force exerted on the clamp holding it in place.

Completely unscrew the nut that holds the clamp closed, put a drift onto the end of the clamp so that you are tapping the two ends of the clamp apart (hard to describe, but I hope you see what I mean) and you should find with a couple of gentle taps the clamp comes loose and can be pushed around the exhaust. Then you need to gently bend it to open it far enough to slip off the flange so it is just on the Y piece. Personally I'd have done this before trying to undo the manifolds because being able to jiggle the manifold a bit makes it much easier to uncrew the awkward bolts once you've got them started.
