Dinan Middle Exhaust and/or Freeflow Exhaust
I have seen videos with both installed, but anyone happy with the X pipe mid exhaust only? What does the back exhaust add to the sound? Not looking to scare people as I go by, but want to add to the stock (valves open) sound. How much is the valves closed sound effected with the X pipe replacement?
