I have been researching some, and was thinking spintech 9k series true duals added to the genuine mopar CAI might be the best for what I am looking for. I am still a little a hazy on the x pipe, it sounds like that adds a little hp, but I don't have enough info to be solid about that yet. I truly enjoy the sound of dual exhaust but i want the performance to go with it. This would be my first performance based mod, I'm curious what everyone else thought.
