Thanks pro. I usually do my own work but things are so hectic with work lately that I just have to pay someone else at this point. If the rear o2 sensors are longer then that seems like an easy fix. What's the worry over the heater? Would I be better served to try something different? My mechanic was able to make it work with the 90 degree max speed mini cat so the distance is probably about 2".

Here is what I have right now. You can see the mini cats. My thought right now is to take the downstream mini cats out of the header and switch the connections for the 02 sensors. Essentially the downstream sensor would be read as the upstream sensor, while vice versa would be true. By pulling the mini cat out downstream, The upstream 02 sensor would be reading out of the collector rather than the primary tube. Would this work?
