want to put headers on the mazda protege es. the car has two cats on it. i dont want to throw a code. any one experience this. please help. doesnt seem to be many people on the protege thead. i had a civic with only one cat and now the mazda has two and seems to be overkill. what is the best way to go
 
you can buy a high flow cat? if you install obx headers the precat is eliminated, and the other cat can be busted out with a broom stick or with a high flow cat. you will throw a code if you dont do the cel fix but im not sure about the second cat throwing a code
