The shop that will be tuning the car is telling me that it will pass just fine with the twinscroll setup using just the two o2 sensors in the downpipe and the JDM ECU. My only concern was the visual inspection of the emission control systems on the motor. I dont see a problem with the up pipe not having an EGT in it, since the twinscroll setup is completly covered with factory heat shielding.

Thanks for the input.
