Headers with cats will most likely pass the sniffer as long as the cats are good enough. you will get a CEL for the lack of post cat sensors and even sims wont work. sims don't take into effect the leanness that happens when you are off the gas and the RPMs are falling. (That is my current problem). The 2 ways to make it pass with headers and aftermarket cats are moving the post cat sensors to after the cats (my sensors are seized so I can't even do that) or to buy a LC-01 (?) Programmable wideband, and just program it to output the correct readings according to the precat o2 readings
