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.

 

why did you make 3 threads about this?

 

I think you should make 1 more thread

 

i KNOW that question has been answered before...

 

wanted to get answers....dont know where the best place to post would be. still waiting on answers.if it has been posted b4, please send link or response

 

yea i agree

 

i could use that info as well. is there also a better header for the 2.4 than the v2 for a daily driver
