  1. Codes P013A & P013C

    5.7L Exhaust
    2009 RT Challenger with Kooks Headers, High flow cats throwing Codes P013A, P013C intermittently. Any idea why it's throwing these codes? Also has CEL Eliminators on both 02's after cats.

    SRT-8 6.1L Exhaust
    I have been reading post from all over the Internet and still haven't been able to find the truth about LTH and catless mids. Yes we all know about Bigdaddies 02 mini cats and the old spark plug fouler with steelwool trick. The turning off the secondary sensors blah blah, and please no EPA post...
