Simple Question - Am I likely to/sure to throw a CEL with UR down pipe, test pipe (no res, no mini-muffler) & cat back?

it is like a spacer between the o2 senor and the test pipe it just lets the right amount or carbon in there to get a good reading thus you get no CEL 90% of the time. which is better than CEL 100% of the time without the non fouler AMS has them also for about the same price.
