Description

The Flowmaster Flow FX Extreme Cat-Back Exhaust System is engineered for 2015–2020 Ford F-150 trucks with 2.7L, 3.3L, 3.5L, and 5.0L engines. Designed for off-road enthusiasts and performance seekers, this system delivers a deep, powerful exterior sound while maintaining a moderate interior tone for comfortable driving.

Constructed with 3.0-inch mandrel-bent 409 stainless steel tubing, the Flow FX Extreme system features a Flow FX series muffler for increased performance and signature Flowmaster tone. The dump-style exit immediately after the muffler eliminates the over-axle tailpipe, improving ground clearance and departure angles in extreme off-road situations. The system installs easily using factory hanger locations, with all hardware and instructions included. Backed by Flowmaster’s Lifetime Limited Warranty, this cat-back exhaust is ideal for Ford F-150 owners who demand performance, style, and durability.
