If the O2's don't get to operating temp quick enough for the DME it lites the CEL & logs a P code.

Would this mean moving the catalyst elements out of the header and to the secondary pipe section would result in improper heating time?
I was thinking about straight headers and Fabspeed cats in front of the muffler would give a better exhaust flow set up.
This would involve putting in long o2 sensor wires and shielding them from heat.
Has anyone successfully accomplished this without getting coded
