Question-Exhaust

I know it is not advisable, but I was wondering if I cut off my Cats on my Mustang will it trip any sensors on the car?, and has anyone else cut off their cats?

Thanks

You're rear O2 sensors will trip a P0420/P0430 (catalyst efficiency) code. Won't affect performance but it is annoying.

I have a DiabloSport Predator, is there any way I could use that to turn off the code?

No... Only a tuner could disable the rear O2s for you.
