Nice Doug! So, how much tonnage did you drop by going to the LV pipe? The stocker, which I assume as a cat in it, looks heavy.
Funny about the ECU flashing a code when you unplug the O2 sensor. The FZ1 simply defaults to a rich base map with no O2 in the loop. The poor man's mod is to simply unplug the O2, open up the airbox, knock out the cat and mount a cheap slip on. This is not optimal, but pretty good - probably 10 hp worth from the mid through the top end
