Easy to install the hardest part for me is understanding the instructions after I read it three or four times it was a breeze

Gibson makes a top notch product equal too or exceeding exhaust systems that are supposed to outperform them. This exhaust is high quality and great sounding without the neighbors hearing you from 2 blocks away. HP gains were noticed immediately. Response was awesome and there was a noticeable increase in MPG. Great product at a great price. Installation was a breeze. Highly recommended.

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.
