Hi All,

I moved in from NJ to CA couple of weeks back and I took my vehicle for a smog test and it failed. I have a 2001 honda civic lx with aem intake, dc sports header and an aftermarket catalytic converter with dual exhaust.. please help...

Any help would be really appreciated..
Thank you all

what did you fail on ?

 

its the cat.... u have to have like a stock one that actually does what it is supposed to,not just for performance....just put a stock cat back on for the test and then change it back after you pass

 

thanks for your repsonse..well the guy who did smog said the O2 sensor supposed to be one in front of the cat and the other one back of the cat where as in my xase both the sensors are i guess infront of the cat. I dont have a stock cat, the reason being is my old cat life was over and i had to replace the cat and the stock cat costed me way over than the performance cat. is there any way i could pass my test with the current setup w/o doing any change..?

thanks for your help

 

It's failing because at the very least, it is obviously modified. I think you'd need to have the second sensor after the cat or it's going to set the CEL. Maybe if it looks right and the stuff coming out of the cat satisfies the sensor so the light stays off, it'll pass.

 

no, I know this, and I don't even live in California

 

Thanks guys. I will try to put the other sensor in the back of CAT and hope my check engline light doesnt come off..
