My NOX is like 2300 and the limit is like 800. I removed my AIVs during the swap. The first time I tested I had no emmissions control what so ever, but tested to see how much over I was. I failed all the tests royally. On the retest I put the mid pipe section with the main Cats back on and passed everything but the NOX still in the high 2200 range. I guess I need to put the precats on and the mid pipes to pass. Hopefully I wont have to reinstall the aiv shit, but as Bernie points out that is more less a non issue after the car is warm. I am trying to find other "creative" ways of side stepping emmissions, I have until the end of this month when my temporary registration expires.
