or buy an o2 simulator if you want to keep it the way it is. what an o2 simulator does is "tricks" your ecu to read the airflow going thruout your exhaust is fine and correct when its really not. only solution i can think of unless you want to put a cat on.
theirs the $20 ones or the exspensive $50+ ones, your call...
