Removing the exhaust

[Skyedriver]

I did this 11 year ago on another Chimaera but on my latest car,
I have removed the clamp off the Y Piece, undone the 6 bolts on the tray and the nut on the rear hanger.
So in my mind it should just pull off the Y Piece BUT, the silencer box hits the anti roll bar.....
Where am I going wrong please...?
It's a decat Y Piece and sleeved exhaust.

Last time I did one (2003), I'm sure I didn't remove the ARB.
The bracket to the block seems to have been hacked off/removed
The connection to the Y piece is free, but the system only pulls back about 25mm
It's all gone back together for the minute.....
