I need a set of low mileage stock headers/pre-cats for my 2004 I35. I have OBX headers/y-pipe on and can't pass smog in CA. Willing to do an even swap install at Finishline in Gardena if you're local. Thanks.

 

Are you failing visual or functional tests?

 

Sorry to hear about the trouble. I have oem manifolds but not cats. I have headers already but maybe we can work something out. Pm me.

 

Functional tests- HC failed 15 and 25mph tests. 20 points over on 15mph and 4 points over 25mph

 

^Those seems like Nominal Differences in HC readings. Although Over; iv passed on the border before after some over the shelf products that may help. Im local in socal; id consider use of my exhaust components for a fee/ then you return to obx.
In sd area other smog "help" may be avail......

 

lol ny easer... no check engine light u pass )

 

On a 04 you should be only obd2 test and not tailpipe. you need to find a shop that has the new equipment. if you have no check engine light on and all the monitors have passed you should pass.

 

California...they're greedy ********.
