You can install everything besides the DP's for that you need something to surpress the O2 sensor cat warnings.
you will have a slight bump in performance, but almost 100-150whp below your potential.. assuming AWD turbo's are a kind of stage 2 turbo's. It would almost be criminal to not have a tune with such a config.
Consider Cobb or procede... altough pretty sure that tje JB4 could do the job.
