Hey everyone! I recently had a Pro-1 Header installed on my 02 IS without using the race pipe. Thereby retaining a single cat on the car. However I am still throwing a CEL.

I know my options are an SAFC or an O2 simulator. Here is my dilemma. This car is a lease and when the header was installed the factory header was damaged. Therefore I plan on returning the car with the Pro-1 Header installed.

Now as a long term fix do I purchase an O2 simulator (and if so how many? Do you need one for each o2 sensor?) The SAFC doesnt seem practical because I am not going to return the car with it still installed.

Let me know your opinions.
