speaking of headers...i have Megan headers and i have to get my car smoged. now there aren't any CARB numbers or anything...will that automatically fail me on the SMOG test?

 

its almost worthless to put the 2nd o2 sensor in bcuz it throws off the ecu, bcuz there is no cat. on my application i personally used a bolt that they gave me and put that in the replacement and i noticed that it ran slightly better. but the check engine light will still come on.

 

dude this thread is like 2 years old, i don't think anyones checking it anymore....

and to cure the CEL get an o2 simulator

 

Yes!!! You will definitely fail here in California. That's the reason I got some DC Sports Header. They are the Only one's that will pass emission here in Cali. Unless you go to a shop who don't care if it don't have the CARB #. I also live in the Southland..Riverside
