She has nothing done to her besides flowmaster muffler, not quite sure which one do to the fact that my father put this on their before i got it... I will be thankful for any help i can get from anyone. I'm a big fan of mandatory work, Life motto Better to be the ugly bastard winning races then the pretty boy sitting on the sidelines. So if you have any performance issues or anything i should be looking for that you know goes wrong with this truck at 161,000 miles let me know.
