Description
Overview
The Flowmaster Force II Cat-back Exhaust System is built for the driver who wants a subtle, custom appearance paired with all the real-world benefits a Flowmaster cat-back delivers. As a S.O.S. (Single Out Side) design, it hits the sweet spot between performance and refinement — offering a moderate exterior tone with a mild-to-moderate interior tone that never overwhelms the cab. If you want efficiency gains without a lot of noise, the Force II series is engineered exactly for you.
At the heart of the system is a large 3.00-inch mandrel-bent aluminized steel design that flows into a 70 Series Big Block II muffler (part number 53073, included) for that signature deep, mellow tone Flowmaster is known for. The generous 3.00-inch inlet diameter and free-flowing path help unlock better breathing so your engine can perform the way it should.
Key Benefits
Like all Flowmaster systems, the Force II is about more than sound. Expect improved throttle response, added power, and better mileage — the kind of everyday gains that make a real difference behind the wheel. The single tailpipe is finished with a turn-down style tip cut into the tubing, which routes exhaust downward rather than outward. That exit location is especially recommended for towing, since it keeps exhaust off your boat or trailer.

Installation & Fitment
Designed for an easy fit, the Force II system uses the factory hangers and includes all necessary parts and hardware for a quick, bolt-on installation with U-Bolt clamping. The 3.00-inch tailpipe drops right into place so you can spend less time under the truck and more time driving it. This 4WD-ready system is designed to fit Standard Cab / Long Bed trucks only, so confirm your configuration before ordering.
Note that the muffler is included, while exhaust tips are sold separately, giving you the freedom to finish the look your way. A heat shield is not included. Please also be aware this product carries a California Proposition 65 warning.
For anyone chasing a subtle custom appearance, a satisfying deep tone, and genuine efficiency improvements, the Flowmaster Force II Cat-back delivers a balanced, towing-friendly upgrade you can rely on mile after mile.
