    Review & Install Video

    Punched-Up Sound. Scream down the road with a punctuated, roaring exhaust with this Force II Cat-Back Exhaust System made by Flowmaster. This exhaust system, complete with mandrel bent tubing, improves the exhaust flow of the F-150 for a noticeable difference in power. The included Pro-Series Muffler will increase the sound of the exhaust with a deep throaty note that announces your arrival.

    Powerful Performance. This Cat-Back replacement exhaust includes the Pro-Series Muffler, which completes a system that creates the throaty sound. After the kit is installed, it removes a great number of restrictions found in the stock system for increased horsepower and more torque.

    High Quality Construction. Created proudly in the United States, the Flowmaster Force II Cat-Back Exhaust is made with the best 3 inch inlet/dual 2.5 inch outlet 16 gauge 409 stainless steel tubing. This metal is corrosion resistant, and comes with 3 inch diameter stainless steel tips, polished to perfection. The tips are emblazoned with the “Flowmaster” logo to give your truck added style.

    Simple Installation. The Flowmaster professionally engineered kit was created to be an exact upgrade, replacing the stock exhaust on the F-150. The kit has all the necessary hardware to help install the kit with only basic hand tools. There are no modifications necessary. Your truck will be roaring in a short afternoon.

    Application.This Flowmaster Force II Stainless Steel Cat-Back Exhaust is designed to fit on all 2011 to 2014 F-150s powered by the 3.5L EcoBoost engine.

      Good system

      Very good exhaust system for a eco boost engine. The difference in gas mileage is definitely noticeable. Looks great and sounds good.
