98 prelude non sh high flow cat/ throwing code / 02 bypass???????
i just put a high flow cat on my girls car and now a check engine light due to the second 02 sensor sensing to much exhaust flow....... is there any 02 bypass tricks????? so the check engine light never comes on again???????

yeah you can either get an o2 sim. or you can do the two defoulers connected putting the o2 sensor away from the flow.
