Description
Overview
The Flowmaster Force II Cat-Back Exhaust System is a complete, performance-driven upgrade engineered for 2015–2020 Ford F-150 trucks equipped with the 2.7, 3.3, 3.5, and 5.0-Liter engines. Built around Flowmaster’s proven Super 50 series muffler, this cat-back kit is designed to unlock better exhaust flow, add usable performance, and deliver a refined tone that suits daily driving, long-haul road trips, and heavy towing alike.
At the heart of the system is a 3-chamber Super 50 muffler featuring a dedicated resonance chamber that tames interior drone and cabin noise. The result is a moderate to mild sound level — assertive enough to signal the upgrade, yet civilized enough to keep highway miles and towing situations comfortable. If you want more capability without an obnoxious cabin, this is the sweet spot.
Flow, Materials & Construction
The Force II is built from mandrel-bent 409 stainless steel tubing that steps from a 3.0-inch inlet down to dual 2.5-inch outlets, maximizing exhaust flow while resisting corrosion for the long haul. The 23-inch Super 50 muffler uses a center inlet with dual 2.50-inch outlets, and the whole system is finished in a durable silver pipe with a black muffler. Topping it off are larger 4.0-inch polished stainless steel tips with an embossed logo for a clean, custom look at the bumper.

Bolt-On Installation
This is a true cat-back system that includes the Super 50 muffler and all necessary hardware. It mounts using the factory hanger locations, so installation is straightforward and requires no cutting into permanent factory mounting points. That means you can get the upgraded flow, tone, and appearance with a manageable at-home or shop install.
Fitment
Engineered specifically for 2015–2020 Ford F-150 trucks with the 2.7L, 3.3L, 3.5L, and 5.0-Liter engines. Because it is CARB compliant, it’s a smart choice for owners in emissions-controlled states who still want the performance and sound benefits of a premium cat-back exhaust.
