Yes the ecu must have the stock tune in California, I’m not worried about passing smog as I know someone who does hot smogs. So passing smog isn’t a worry for me. I am going to cat delete and add some big slp mufflers and run cut outs right before it that way I will essentially be straight piped but with the small resonators, basically the same thing so no issues there right? Or does it need to right after the turbo instead of having it straight piped
