Description
Overview
The Flowmaster Flow FX Direct Fit Dual Mode Muffler brings split-personality performance to your RAM 1500 with the 5.7L Hemi. Built around Flowmaster’s W.A.V.E. Technology (Wireless Active Valve Exhaust), this dual-mode system delivers a refined performance tone over the stock exhaust in everyday driving, then transforms into a deep, open exhaust note the moment you activate the wireless valve. It’s the best of both worlds: a moderate, mannerly cruise or an aggressive, unmistakable roar, all controlled from the palm of your hand.
Engineered as a true direct-fit replacement, this system pairs a round Flow FX performance muffler with a Power Chamber that houses a wireless-controlled active by-pass valve. When engaged, the valve redirects exhaust through a large 3.00-inch turndown dump-style tailpipe, letting everyone know who the Boss is. When closed, the Flow FX muffler keeps things tuned and civil.
Key Benefits
Every component is designed for a bolt-on experience. Mandrel-bent 409 stainless steel construction flows smoothly into the Power Chamber, followed by the round Flow FX performance muffler that connects easily to the factory tailpipe. Because it uses the factory hanger and mounts in the OEM exit location, installation stays straightforward while the included clamps, hardware, and detailed instructions keep everything ready to go out of the box.
- Full 409 stainless steel body, tubing, and 3.00-inch turndown tip for lasting corrosion resistance
- Wireless Active By-Pass Valve with actuator motor, control unit, and two wireless key fobs
- 3.00-inch mandrel-bent main piping for smooth, consistent flow into the Power Chamber
- Dual-mode sound: moderate performance tone closed, aggressive open exhaust when activated
- Offset inlet and offset outlet, OEM-style exit, and factory-hanger mounting for a direct fit
- Clamps, all necessary wiring, hardware, and detailed instructions included
The Active Valve Explained
At the heart of the system is the Power Chamber, which contains a high-quality wireless-controlled actuator valve. With a simple push of a button on either included key fob, the valve opens and routes exhaust through the 3.00-inch turndown dump-style tailpipe for that deep, open sound. Release the valve and the Flow FX muffler returns you to a controlled performance tone. The actuator motor, control unit, and wiring are all part of the package, so the dual-mode functionality is complete from day one.
Fitment
This system is designed for 2019*-2024 and 2026 RAM 1500 (*new body) trucks equipped with the 5.7L Hemi engine. It fits trucks with a factory single tailpipe or trucks with the factory dual tailpipes. Please note this configuration does not include a heat shield or tip logo, and carries a California Proposition 65 warning.
