Also, the 3 bolt flange uses a donut gasket, not that flat thing. Get new gaskets from the dealer. If the aftermarket cats you got don't use the factory style gaskets, you got cheap Chinese cats. Send them back and get proper ones.

So I sent back the other cats and now waiting on the new ones. So another question. If the cats have to be for an HR motor does the 02 sensors have to be as well.

Yes, all four are different between HR and DE. But why does it matter of you’re installing the correct cats and can reuse your existing four sensors?
