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
