Had the car for a year and have my first emissions coming up by January, wondering if I'll pass. I have a test pipe (primary cat delete) and exhaust. Also have Alex's Alpine stage 2 tune, so no check engine light on or anything due to his software clearing those. Anyone have this type of setup that can let me know if I'll pass emissions?

You could move south to a state that doesn't have nanny state restrictions. Just saying…

I didn't know we were required to have emissions tests. Can you elaborate?

Does Illinois check the readiness monitors? If they do, O2 readiness will not set without primary cats. If you are allowed to have one monitor not set in order to pass you should be good. Here in CA i think you can pass with one monitor not set but it cant be the O2. If your state doesnt check for Readiness, and only checks for faults/CEL, and doesnt look under the car you should probably be good.

To be clear, this only applies to Chicago and Metro East and not the entire state.
