Put a hose clamp around the crow foot. Also: for post cat: remove the vibration damper for much better access on the downstream sensors.

I use the crow foot with a wobble extension from below (extension in the opposite normal side) it works like a charm with impact wrench to start it.

You can also use a hammer on crow foot if don't have impact.
