My truck already had a K&N servicable filter along with a tuner program installed. After the installation of my flowmaster cat back system I noticed a smooth increase in power and smoother transmission shifting. I have not done the mileage yet but my 5.4L has 150,000 and was already getting 14.75 MPG. I will add one of these to my wife's 05 V-6 Mustang next.
