well I search some of the threads but didn't get the answer I was lookin for. so I installed some jba long tubes, and got the extentions for the 02 sensors. and now I have a check engine light, and the codes are p0420,p0430.. I emailed G but no reponse yet so I figured I would try to get yall's opinion.. are these codes because of the deleted cats, or could it be something else... I got the extentions for the 02 to try to avoid the CEL... I have cleared the light a couple times but keeps comin back on...
