If all you change is the stage 1 exhaust, do you really need to unplug the 02 sensors? I ask because I hear and read there is not much difference in stock and stage 1. The long range plan is PC5 and Lloyd's air filter, but for now I just have the pipes. Kyle is only close enough 2 times a year at Myrtle Beach, so timing is a big influence on when and what I do. I don't have enough cash right now to do everything before the rally in 3 weeks and I don't want to wait 5 months until he comes around again to put on the pipes. Unplugging the 02 sensors for 5 months is also not part of the master plan as I do most of my riding during this time. What do you think? Just asking an open question......
