only reason I suggested the cat delete is its one less CEL / reason to fail an inspection. Doesnt mean you need to remove the cat, it just tells the computer to forget that downstream O2 even exists.

Like the stage 3 from Uni, or Eurodyne… they delete just about everything and hard set readyness to pass… you could have a gerbil on a wheel under the hood powering the car and it would pass inspection with flying colors (electronically that is).
