I have a 97 Cobra that I cannot seem to get to pass smog in CA. My NO (NOx) numbers are really high. I have a chip in the Car with a tune (Powertrain Dynamics EEC-V Dyno Chip). I called them up and they stated that the tune was set with a 12.8 A/F mixture (Rich). I have checked the PCV valve and it works. I do not have my check engine light on so I am asming that my EGR Valve is working and my O2's are too (anyone know how to check this)?. The only mod that I can think of that is causing my elevated NOx levels is my Bassani Catted X-pipe. I have a line on a 01 Cobra H-pipe. Will it fit on a 97 cobra or are the bolt pattern and mounting poits different? I need a stock one to pass the visual inspection.[/align]

 

anyone?

 

Not positive but i dont think it'll fit.. i would ask for another opinion tho.
