Hello all!! I've been thinking of doing this for long time as stated.....gutting the cats and leaving them on the car. After being told by others on here that it would set off a check engine light would it be possible to buy aftermarket mils made for mustangs to solve this problem? The mils for mustangs solve the problem for them doing same thing was wondering if it would be inter changeable and work on our cars? Thanks!! BTW-have not done anything to car yet but i want to real bad but need to know how to get rid of light if it sets off besides buying an expensive tuner. I have a year till next inspection but don't want a check engine light i can't get rid of.
