I know I'm about to get shit on, but here it goes. THIS IS FOR TESTING PURPOSES ONLY.
I'm looking to replace the factory exhaust manifold and precats with an APN header. There would be 1 O2 bung in each 3 cylinder bank, then I would extend the wiring of the downstream O2 sensors and place both after the main cat before the muffler.
Question: can anyone see why this would not work without CEL?
Would it be easier to use a 1998 ecm and eliminate 1 upstream and 1 downstream O2 sensor?
