Description
Overview
The Flowmaster Force II Cat-back Exhaust System is engineered for the F-150 owner who wants a genuine performance upgrade without an aggressive, droning cabin experience. Purpose-built for 2009-2014 Ford F-150 trucks running the 4.6L, 5.0L, and 5.4L engines, this complete single-exit system delivers a moderate exterior sound level paired with a mild interior tone, so you get the unmistakable Flowmaster presence outside while keeping long-haul comfort inside the truck.
At the heart of the system is a Super 50 Series muffler that flows into a large single 3.00-inch mandrel-bent tailpipe. Every section is built from stainless steel with true mandrel-bent construction, maintaining smooth, consistent diameter through each bend for optimal exhaust flow. The system is capped off with a polished stainless steel 3.50-inch tip that adds a clean, finished look at the rear of the truck.
Key Benefits
Like all Flowmaster systems, the Force II is designed to unlock real-world gains you can feel behind the wheel. Owners can expect improved throttle response, added power, and better mileage compared to a restrictive factory setup. Because of its balanced tuning and free-flowing design, this system is especially recommended for towing applications, where consistent power and manageable sound levels matter most.

Fitment
