Flowmaster FlowFX Active Dual Mode Mufflers

Flowmaster FlowFX active dual mode mufflers allow your exhaust tone to be mild or wild. With their split personalities, these direct-fit mufflers offer a nice performance tone—as well as a deep open exhaust sound with just a push of a button, thanks to the wireless controlled actuator valve on the Power Chamber, which redirects exhaust through the turndown. FlowFX systems feature mandrel-bent stainless steel construction, and include actuator motor, control unit, two wireless key fobs, all necessary wiring, hardware, and detailed instructions.
