1500Ram9987 will become famous soon enough

the rear 02's only monitor the you will have to disable them (diablo or custom tune), or run something like plug foulers (see pics). If you tune them out, they will have to be turned on for emissions testing (at least in Cali)
Does a diablo performance tune automatically do this or is it an option somewhere in the tool that I just haven't found yet?

Why do you want to remove them? They hardly rob you of any power...
I can't answer for Daytona, but as for me... I'm not setting out to simply remove my cats. Pacesetter sells a set of LT headers and matching y-pipe that I have been eyeing. With these two items, the cats would have to either be relocated or deleted... and being in a state where we do not have to worry about emessions testing, why not get rid of them?
268 Comp Cam, Coated Pacesetter LT Headers, Y-pipe, Custom Exhaust, K&N CAI, Edge Billet 3000 stall TC, 4.10s, Auburn LSD, E-Fan, 180* t-stat, tapered/bored Fastman TB, 20% UDP, DSP, Hemifever Custom Tune
