As long as you don't touch the main cats you will have no issues at all. There will be no change in idle, no CEL and it has no effect on passing your inspection. If you get a sniff test as part of your emissions test I believe you will still pass no problem because the secondary cats are only for start-up emissions reduction. WA state does a OBD2 test only, so there is no problems with the mod as its post the o2 sensors.
