Marble mod with 02 sensor???

[Dozerdriver]

I have a full exhaust with the 02 sensor and stock ecu. Can I do the marble mod with this set up? I am getting a pc III or Bazzaz soon but for now wanted some popping to go away? Thanks..

yep or ducttape works in a pinch

Does the 02 sensor need the extra air?

What is the marble mod and do you need aftermarket exhaust to do it?
