So I'm thinking about replacing my DD "Cleadus", my 96 Cherokee. I've been seeing 2010-2014 former police chargers for under 10k and under 100k on the clock. I have no experience with the 5.7. Way better mpg than Cleadus. Should I go this way? What mods should I do that are low buck should I get one? Mid muffler delete or resonators?
