I'll have to keep the o2 sensor replacement in mind for later down the road, better to do it ahead of schedule. I just removed my High flow cat and put my oem cat back on the car. The 02 sensor was covered in some soot/carbon, I cleaned it off before reinstalling it.

On a side note I got my used oil analysis back after my trip to the Dragon. Wear numbers didn't look much different than a typical street driven comparison which is pretty damn good given the conditions the engine undergoes at the Dragon - high rpms , high g-forces, tons of WOT. Best part is that fuel content in the oil was negative.
