Engine Codes 0420 and 0430

I just had my JBA Ceramic Headers installed with a hi-flow cat x-pipe. On way home from shop everything was fine. Just took car out for another ride and was kind of hot-rodding around and check engine light came on with these two codes. Is this going to keep happening?

There is a list of codes somewhere, just search it. I'm sure requesting a new tie will take care of them.

Any specific tie? I have muffler tape and that didn't work, I have tried hitting the exhaust with my glass hammer and that didn't work either, I'm now drinking beer from my left handed mug trying to figure out if these two codes will keep coming back.

You'll need to have your rear o2's turned off even though you have cats. Those cats are just too efficient. Hope you don't have to go through emissions.

Neither. The tune. Once you turn those codes off the readiness test will fail you in most states.

I have had JBA LT's and JBA catted X for about a year, no problems. Just get with Bama to revise the tune
