Replaced cat, O2 sensors and all valves. Very slight crossover pipe leak starting.
Terrible rattle (sound like jackhammer) which occurs once in a while after warmed up (usually when warmed up and idling - when giving it gas again - it disappears after a few seconds), gut it really is a load jackhammer sound. Dodge can't find anything loose.
71,000 miles on it.
