Product Details

Introducing the new Flow FX Active Dual-mode muffler featuring our new W.A.V.E. Technology (Wireless Active Valve Exhaust ) for all 2019-2026 GM Silverado/Sierra 1500 (new body style) with 5.3L engine.

This direct-fit replacement muffler has split personalities with a nice performance tone over the stock exhaust system, thanks to the Flowmaster Flow FX performance muffler. The system also features a high quality wireless controlled actuator valve on the Power Chamber redirecting exhaust through the turn down, giving you that deep open exhaust sound with just a push of a button. System features include mandrel-bent stainless steel construction leading into the Power Chamber, followed by a round Flow FX performance muffler that easily connects to the factory tailpipe. The Power Chamber houses a wireless controlled valve with a large 3.00-inch turndown dump style tailpipe letting everyone know who the Boss is once activated. Other system features include actuator motor, control unit, two wireless key fobs, all necessary wiring, hardware, and detailed instructions. Maximum dyno gains of 9 hp and 11 lb.ft. at the rear wheels. Note: Fits 2019 (New body) 2/4 wheel drive and all wheelbases.
