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 of a genuine Flowmaster cat-back upgrade. As part of the S.O.S. (single out side) family, this Force II system delivers a moderate exterior tone matched with a mild interior tone — an ideal balance for anyone chasing efficiency improvements and cleaner power delivery without a loud, aggressive cabin drone.
At the heart of the system is 3.00-inch mandrel-bent 409 stainless steel tubing that flows into a proven 50 Series Big Block performance muffler. Mandrel bends preserve full pipe diameter through every curve to maximize exhaust flow, while the 50 Series Big Block muffler is tuned to deliver a moderate exterior tone with a mild-to-moderate interior tone and maximum power. The result is a refined sound signature that lets you enjoy improved performance without sacrificing everyday comfort.
Key Benefits
Like all Flowmaster systems, this Force II cat-back is engineered to improve throttle response, power and mileage. The single tailpipe exits behind the right side rear wheel — a purpose-built design detail that makes this system especially well suited for towing. By routing exhaust behind the wheel, it helps keep smoke and fumes off your boat, trailer or cargo when you’re hauling, so you get performance gains without the nuisance.
