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 performance benefits of a genuine Flowmaster cat-back setup. This single-outlet system upgrades your factory piping with all stainless steel 3.00-inch mandrel-bent tubing that flows smoothly into a Super 50 Series muffler, delivering efficiency gains without turning heads for the wrong reasons.
Engineered around the Force II design, this system produces a mild tone both inside and outside the cab. It’s an ideal choice for owners who want improved breathing and a cleaner note without the aggressive volume of a race-style exhaust. That refined, understated character makes it especially well suited to towing applications, where you want power on tap and a comfortable cabin over the long haul.
Key Benefits
Like every Flowmaster system, the Force II is designed to sharpen throttle response, free up power, and help improve mileage. The 3.00-inch inlet and mandrel-bent tubing keep exhaust flow smooth from the cat-back forward, while the Super 50 Series muffler tunes the sound to a mild, drivable level. A large single tailpipe is finished with a 3.50-inch polished stainless steel tip for that subtle custom look at the bumper.

Sound & Performance Character
The Force II strikes a deliberate balance. Where some systems chase maximum decibels, this one delivers a mild exterior and interior tone that keeps highway cruising and daily driving quiet and refined. That’s the whole point of the Force II series: real efficiency and performance improvements without a lot of added noise. If you tow, haul, or simply want a better-sounding, better-breathing truck that still feels civilized, this system fits the bill.
Fitment & Installation
Designed for an easy, bolt-on fit, the system reuses the factory hanger locations so it drops into place without cutting or custom fabrication. Every kit ships complete with the parts and hardware needed to get the job done. This application also fits 2009-2013 GM Silverado/Sierra 1500 models with the 5.3L engine in Extended Cab/6-ft bed and Crew Cab/5.5-ft bed configurations, and is set up for 4WD trucks.
Backed by Flowmaster’s Lifetime Limited Warranty, the Force II Cat-back is a confident, long-term upgrade. Please note this product carries a California Proposition 65 warning.
