Emissions in IL
Hey guys, not sure if this is the correct subforum to ask but my car is due for emissions in a couple months. In IL, they only do obd testing. I'm currently running a catless dp on a custom 93 tune. What's needed to pass? Should I reinstall the stock dp and go stage 0 on mhd? Currently the catalyst system is turned off within the tune. I've had luck before on other cars using a o2 defouler to space out the rear o2 but don't remember if there's enough room to install it or not. Any ideas would be great. Thanks
Car is a 2011 if that makes a difference

I just re-installed the factory dp since its easy on the n55. I have all the monitors ready now except for the evap. I believe i was told IL allows one readiness monitor to be not ready so i will give it another try this week and hopefully will pass.
