As for installing DP, can you just upgrade it without doing a ECU tune? Im leaning towards just doing DP & JB4 to begin with, then do the IS38 later. Have already done the resonator delete.
If you don’t get a tune with a DP and highflow cat you most likely get a cat efficiency CEL. I’m not familiar with a JB4 and whether it can remove the CEL, I know most tunes code this CEL out. Perhaps an O2 sensor spacer like a Vibrant J spacer might work.
