P0430 Code After Kooks Install
Has anyone else seen this? Put 122miles on the car after the header install and saw nary a code. Took great care with the 02 sensors during the install too.
I did a little research both here and at LS1 Tech. Seems that this code can come up with long tube headers and/or high flow cats. The posts I read were somewhat old, but back then, some recommended editing this code out.
Whats the consensus now?

Reset the code, a couple times if needed, then see if it continues to come back. If so, I would just turn it off..
I've become the master of turning off codes lately...
Except for the 2 that LS1 edit thinks are disabled, but still set... and Ken @ Carputing is ignoring me on those issues.. So if you don't have tuning software, and are looking to buy it, I would now recommend HP Tuners.Good Luck.

I got the voltage codes after my Kooks LT's and cats. I reset them many times and they eventually came back. Apparently, the code trips because the exhaust flows so well that the rear sensors don't get hot enough...or something 
. I had the rear sensors turned off when the car was tuned. Chris.
