    In some areas they do random roadside emmission checks and if your car fails you get a hefty fine

    If You don't want cat...and Your gonna use car on track or You are not scared of police

    You can remove both cats... It's possible to turn off 2nd lambda when remapping then there is no problem wich check-engine light
