99% of folks get the p0420 &/or p0430 code with headers, the cat inefficiency codes.
I have read herein that a few users have been able to avoid the by wrapping their headers but I am dubious.
The easy answer is to find someone with HP tuners, pay the $99 to license your car and turn off the reporting for this codes. Your car will run and no check engine light...but it won't be optimal by a long shot.
The factory tune is not optimized for headers. You will notice a very nice gain from the tune, particularly in the summer.
