Description
Overview
The Flowmaster Force II Cat-back Exhaust System is a complete bolt-on upgrade custom designed for 1998-2003 Dodge Durango models equipped with 4.7L, 5.2L or 5.9L engines. Engineered for drivers who want a noticeable step up in sound and performance without going over the top, this Force II system delivers a mild-to-moderate tone inside and outside the vehicle while adding the flow and character Flowmaster is known for. It fits both 2WD and 4WD Durangos and mounts using the factory hanger locations for a clean, integrated fit.
At the heart of the system is the 70 Series Big Block II muffler (part number 53070), tuned to produce a deep, mellow tone that stays refined at cruise and comes alive under throttle. A mandrel-bent aluminized steel inlet pipe feeds the muffler, and a single mandrel-bent aluminized steel tailpipe carries exhaust out the back, finished with a brushed stainless steel turndown-style tip that exits below the rear bumper for a subtle, factory-plus look.
Key Benefits
Mandrel bends keep the piping smooth and consistent in diameter through every turn, promoting better flow than crushed factory piping. The result is improved exhaust performance paired with a moderate sound level that won’t drone on long drives. As a true cat-back system, it replaces everything from the catalytic converter back and bolts on with the included hardware.
