Description
Overview
The Flowmaster Force II Cat-back Exhaust System is built for the driver who wants a subtle custom appearance combined with all the real-world benefits that a Flowmaster cat-back system delivers. This Force II system is constructed from mandrel-bent 3.00-inch aluminized steel tubing that flows smoothly into a proven 70 Series Big Block II performance muffler, keeping things mellow inside the cab while still freeing up the exhaust flow your engine wants.
Everything about this system is engineered for a clean, factory-style fit with an upgraded attitude. The 3.00-inch tailpipe is finished off with a large 3.50-inch polished stainless steel tip, giving your vehicle a purposeful look without the drone. With a mild sound level, the Force II keeps the interior comfortable for daily driving and long hauls while delivering the deeper, refined tone Flowmaster is known for.
Key Benefits
Like all Flowmaster systems, this Force II cat-back is designed to improve throttle response, power, and mileage. The mandrel-bent tubing maintains a consistent 3.00-inch inner diameter through the bends, promoting efficient flow, while the 70 Series Big Block II muffler (part number 53073) keeps sound levels mellow inside the cabin. It’s a smart upgrade for anyone who wants performance gains and a custom exhaust note without an aggressive, loud interior experience.

Fitment
This Force II cat-back fits both 2 and 4 wheel drive models and all wheelbases, making it a versatile choice across configurations. Please note the California Proposition 65 warning applies.
