Nothing is more mundane than a stock vehicle with a factory exhaust system. And while a quiet exhaust is nice in some cases, performance mufflers offer less restriction, which often equates to more horsepower. Now you can have the best of both worlds for the 2019-2021 GM Silverado and Sierra 1500 trucks with 5.3-liter engines.
Flowmaster’s latest product is the FlowFX Active Dual-Mode muffler featuring our new wireless active valve exhaust (WAVE) technology. The new muffler is a direct-fit replacement that can go from mild to wild at the touch of a button. This system features a high-quality wireless controlled actuator valve on the Flowmaster Power Chamber. When activated, the actuator will divert spent exhaust gasses through the turndown, giving your truck an aggressive exhaust note at a moment’s notice.
The Flowmaster FlowFX system offers mandrel-bent stainless steel construction leading into the Power Chamber. A round FlowFX performance muffler is also attached, which connects to the factory tailpipe for easy installation. The Power Chamber contains a wirelessly controlled valve with a massive 3-inch turndown that will turn heads when activated. Another great thing about this system is it will fit all 2019 and up to two and four-wheel drives and all wheelbases. The Flowmaster FlowFX system includes an actuator motor, control unit, two wireless key fobs, necessary wiring, hardware, and detailed instructions.
Flowmaster’s FlowFX Active Dual-Mode Muffler is a perfect fit for 2019-2021 GM trucks and allows for moderate to aggressive exhaust notes at the push of a button.
