Can anyone give me step by step directions on how to remove the primary cats on an 05 Frontier, 6-cyl, 4.0 eng. Looking at them, the bottom end is easily accessable but I can't figure how to get to the top end (attached to manifold). THANKS IN ADVANCE.

I'm sorry but I don't understand, what is or where do I find "the FSM from the sicky"?

Thanks for all the good advice, I replaced the driver's side primary cat, it was painful, about 4 hours but it was well worth it. The truck is running great now, no more SES light.
