Description
Overview
The Flowmaster Force II Cat-back Exhaust System is engineered for the 2015-2020 Ford F150 owner who wants a mild exterior sound level while keeping a moderate interior tone — all without giving up the performance edge Flowmaster is known for. It’s a complete bolt-on upgrade that transforms the flow and character of your truck’s exhaust, striking a refined balance between everyday drivability and a deeper, more purposeful presence.
Built from durable 409S stainless steel, this system is designed to resist corrosion and hold up to the demands of daily driving and long-term ownership. From the 3.00-inch mandrel-bent tubing to the flanged connections, every component is shaped for smooth, unrestricted flow that helps your engine breathe more freely.
Key Benefits
At the heart of the system is the proven 70 Series performance muffler, finished in black, which delivers Flowmaster’s signature moderate-and-mild sound signature. Exhaust gases flow through the 3.00-inch mandrel-bent piping into the muffler and exit through a 3.00-inch tailpipe capped with a large 4.00-inch double-walled polished stainless steel tip featuring an embossed logo — a clean, aggressive finishing touch that looks as good as the system performs.

Sound & Performance
The Force II series is purpose-built for drivers who prefer a subtle exterior note. Outside the truck you’ll hear a mild tone, while inside the cabin the sound stays moderate — no drone-heavy compromise, just a cleaner, more confident exhaust note backed by the performance gains that come with improved flow.
