Richer or Leaner

Does taking off the stock CATS and replacing them with a test pipe with a resistor make the car run more leaner or richer.

Deleted. I attempted to answer your question, but then saw that you are running NOS.

I thought it was richer. From my knowledge, if you have more air moving in or out of the engine, the ecu will richen the ratio to compensate to prevent detonation or damage. I may be wrong

Not using NOS, just driving around town would it be one way or the other.

Seems to depend on how your ecu responds. For most you would go leaner, but some ecus are compensating and going a little rich.
