if i put a full exhaust on my california emissions model 200sx will i have to change the cpu also to avoid error codes even if i put a cat and an o2 sensor in it where it would b if it wasnt a california emissions model?

if you buy a hotshot header, then it comes with 02 sensor bungs in it already, and is CARB legal as far as i know.

if you buy a stromung exhaust, you have to make sure you buy a cali model exhaust, as they sell diff. models for cali and federal. cali models come with bungs in them as well so you wont need to go and have them welded in.

you wont need to change the ECU, and i beleive the stromung is CARB legal too, but you might wanna look into it
