'04 catalytic converter replacement

[brider]

How do I actually ACCESS the attach bolts for the front and rear cats? I looked underneath, and it looks like there are (2) bolts on the front cat that need to be accessed from the TOP, and at least 1 on the rear cat.

Looks like the front would require radiator removal to get at, and the rear would require ENGINE REMOVAL.

Is there any other way? I can't BELIEVE Nissan would design cat's that require engine removal to replace.

Hopefully someone with access to the Nissan FSM can chime in on this one.

Can you get at the exhaust manifold bolts to get the CC assemblies off? These close mounted ones are tight I know..
