Screw cats.  Knock them out.
Better, custom dual exhaust.
Originally i had the precats knocked out,but with the OB2 system the first oxygen sensor reads the mixture coming out of the motor and the second one after the cat reads it again and if theres no change or its too rich it will lean up the mixture so that would kinda defeat the reason to knock them out.
I thought about a dual system also,but i would need to fabricate a new trans. crossmember because theres no cut out on the passenger side for the exhaust.
For now i will gut the final cat and see how that goes.
Trying to find some easy and low cost mods, I got enough money stuck in this TOY as it is!
