Anyone run or dyno'd BBK's Shorty equal length headers on a coyote 5.0? I live in a county with emissions testing. Leaving the stock cats in place is my safest bet to get through the yearly check. If a go with LT headers and high flow cats, I am not sure whether the ECM will throw a code (readiness check for rear O2 sensors can not be disabled).
