Description
Overview
The Flowmaster Force II Cat-back Exhaust System is engineered for 2008-2013 Ford F-250/F-350 Super Duty trucks equipped with a V8 or V10 gas engine. Built for the driver who wants mild to moderate sound levels alongside the performance gains Flowmaster is known for, the Force II delivers a deep, powerful tone without droning your daily drive. It’s a complete bolt-on upgrade that transforms both the sound and breathing of your Super Duty.
At the heart of the system is the 50 Series HD performance muffler, featuring large 4.00-inch internals that flow more efficiently while keeping the cabin comfortable. Paired with a 3.00-inch inlet and dual mandrel-bent 2.50-inch 409 stainless steel tailpipes, this cat-back exhaust is designed to maximize exhaust flow and free up the performance your truck is capable of.
Key Benefits
Every component is chosen with performance and longevity in mind. The mandrel-bent tailpipes maintain a consistent diameter through every curve for smooth, unrestricted flow, while the 409 stainless steel construction stands up to the heat and elements that Super Duty trucks endure. The system is finished with a pair of large 3.50-inch polished 304 stainless steel tips for a clean, aggressive look at the exit.
