Any opinions greatly appreciated. I have no problem cutting a 4" hole in the right fender well. Really want to know if it makes a difference going with a system using "outside" air such as the Zabteck. Also opinions regarding aftermarket mufflers such as Flowmaster or Borla. I have spoken to several specialty exhaust shops and all three said no appreciable gain in MILEAGE. HP gain is nice but it comes with added "noise". Thanks ST dudes!
