Well I have been on this long debate on whether I should remove my headers or not, and Jim Jr. a JDM suggests it would be better to just put the stock system back on, as they have had problems even with metallic cats not passing. I am from new york and here they do a check through the OBDII port instead of a tail pipe sniffer. I am not sure 100% how this works, but I believe it checks to make sure all the 02 sensors are working properly and making sure your car isnt throwing any codes.... any suggestions on how to pass or even if I find someone to "help me out" will he actually be able to pass me?

 

If you have cats and your emissions system hasn't been tampered with (ie. turning o2 sensors off) then I imagine you should be fine.
