Dude,
It takes 300psi of oil pressure to burst a cannister on a extra gaurd filter. When that happens, it is because the oil pressure relief valve is stuck, usually from sludge. It is not the fault of the filter, it is an internal issue with the engine. If you ever see a bulging filter, its time to drop the pan and front cover and fix it fast.
