I was at 13 mpg. Added superflow cat with 3.5 in. deuls straight out the back with 4in tips. Not omly does it sound fantastic I gained 2 mpg. Just tryin to do what is best for our fossil feul consumption. My next step is cold air intake and I hear getting a chip{hyper tech, jet, ect.} will help. Any one done this mod. Any suggestions.
