Its common to get those codes with the high flow cats,I also got the same codes.i installed srt8 manifolds and magnaflow cats on my r/t a few weeks ago, and am getting codes p013a and p013c i know they have to do with the post cat o2 sensors. i have looked more than once for exhaust leaks but cant seem to find any. does anyone know how to fix this? are o2 sensors damaged easily? maybe i broke them, i did hit the wrench with a hammer to remove them.
any info you guys have would be great thanks

Search for the antifouler mod,or get a custom tune to disable the rear o2 sensors,however you will not pass emissions test with the sensors turned off.
