    Once you have it unbolted go underneath the car and use a extension along with a breaker bar..don't cut it.

    Guys.. he can't cut the bolts at the flange between the cat and the resonator. Reason being is... on a Park Ave, those bolts, that flange............they don't exist.

    Here's the walker diagram. There's no connection point between cat and res from teh factory though. The connection is the DP comes down from the rear manifold and into that square gasket on the front of the cat. That's it
