    Just checked my codes. Got a P0420. Check engine light is off

    This looks like it might be my problem.

    Thanks for all the suggestions. And I got to get it fixed

    So looking it over, it looks like the forward two cats are an assembly, and they are a slip fit into the exhaust, and bolt onto the manifold with ****** clamps.

    I got three O2 Sensors as well, and new plugs.

    Has any one had any recent experience removing their forward exhaust element? Any tips or tricks?

    Thanks -

    Rocky
