header questions...smog legal??... help!
so i am debating if i want to buy the Cobalt addiction V2 headers and xtc downpipe combo. they both have O2 sensor ports built in and what not, but im wondering if they would pass smog. this is my daily driver and need it to pass smog in CALIFORNIA. if anyone knows or has had experiences with passing smog with aftermarket headers/downpipe, please help me and let me know whats up.
