Description
Overview
The Flowmaster Force II Cat-Back Exhaust System is a complete stainless steel upgrade engineered for the 2021-2026 Ford F-150 equipped with the 2.7-Liter, 3.5-Liter, or 5.0-Liter engine. Built around Flowmaster’s proven Super 50 series muffler, the Force II delivers a moderate-to-mild exhaust note paired with increased performance, making it a smart choice for daily drivers, weekend haulers, and long-distance road trips alike.
At the heart of the system is a 3-chamber Super 50 muffler that includes a dedicated resonance chamber to help reduce interior drone. That refined tuning is ideal for towing and long-haul situations where you want a stronger, more purposeful sound without an aggressive cabin roar. The muffler measures 23.00 inches overall with a center inlet, dual outlet configuration, and 2.50-inch outlet diameter, finished in a clean black coating.
Performance and Construction
The Force II uses mandrel-bent tubing that steps from 3.00 inches down to dual 2.50-inch outlets, promoting maximum exhaust flow and long-term durability. Every section is crafted from 409 stainless steel with a silver pipe finish, so the system is built to stand up to heat, road spray, and the elements. The result is a free-flowing dual tailpipe layout that both looks and performs the part.
Custom Look and Finish
Finishing off the system are larger 4.00-inch polished stainless steel tips featuring an embossed Flowmaster logo for a custom, factory-plus appearance out back. The combination of the dual tips and the polished stainless finish gives the F-150 an upgraded, purposeful stance without looking overdone.
Easy, Bolt-On Installation
Designed as a true cat-back kit, the Force II uses your truck’s factory hanger locations for a straightforward, no-guesswork installation. All of the necessary hardware is included in the kit, so you have what you need to complete the job and get back on the road. Because it retains the factory-mounting points, fitment stays clean and secure.
