How are you passing an emission test with long tube headers. I have a tune that is 50 state compliant but I can not get the monitors to turn "OK" after driving 100 miles. I have cats and the rear sensors. IS there someone who could tune my car to pass emissions or is there another way to pass. I have a tune that will turn all monitors to NA and will probably pass but I'm not sure what would happen if I try to get it passed on that tune.
Any help greatly appreciated.
