I've gotten this code twice now and I keep clearing it. I know it has to do with the cat. I recently installed BBK LT with the catted x pipe. Do you think something is wrong with the catted x pipe as its only one side? However, the car runs great and I don't smell any extra exhaust fumes.
Any help or ideas would be greatly appreciated.

 

p0430 means the cat on bank 2 isnt working, bbk may senda replacement cat for free. check your warranty

 

I sent BBK and Brenspeed emails. I'll just wait and see what they say.

 

Possable causes:
Damaged Heated HO2S sensor
Out of range ECT sensor
High fuel pressure
Damaged Exhaust Manifold
Damaged Catalytic Converter
Oil Contamination
Cylinder Misfiring
Downstream HO2S wires improperly connected
Damaged Exhaust System pipe
Damaged Muffler/Tailpipe assembly
Retarded Spark Timing
Leaking Fuel Injector

 

Thanks for the info. Brenspeed said I should try a spark plug non fouler. It will move the o2 sensor farther out of the exhaust gases and perhaps trick the computer.

 

are your rear O2 sensors off? i've heard of a few people w/ catted mid pipes get a CEL like they dont have cats.

 

How about some MIL eliminators for the O2 sensors?

 

No I don't think they are off. Can I turn them off my self or does Brenspeed need to do it?

 

you should be able to turn it off yourself, if brenspeed left the adjustable options on. i have custom tunes which one i can change things, the other 2 i can't. if you cant, brenspeed should send you an email tune w/ them off.
