Product Description

Upgrade your 2015-2020 Ford F-150 with a Flowmaster Flow FX Cat-Back Exhaust System designed to deliver improved exhaust flow, enhanced performance, and the deep, powerful sound associated with the Flow FX series. All three configurations feature Flowmaster's straight-through performance muffler, mandrel-bent stainless steel tubing, factory-style mounting locations, and an installer-friendly design with the necessary hardware and instructions included.

Choose the exhaust configuration that best matches your preferred appearance and intended use. Part #717785 uses dual 2.50-inch tailpipes with dual 4.00-inch black ceramic-coated 304 stainless steel tips exiting in front of the rear passenger-side tire, giving the truck a distinctive muscle-truck appearance. Part #717871 uses dual 2.50-inch side-exit tailpipes with large 4.50-inch black ceramic-coated 304 stainless steel tips positioned behind the rear wheels, directing exhaust away from a boat or travel trailer when towing. Part #717978 uses a single 3.00-inch dump-style outlet, eliminating the over-axle tailpipe for increased ground clearance and improved departure angle, making it suited to applications where off-road clearance is important.

All three systems are engineered for the 2015–2020 Ford F-150 and provide an aggressive-to-moderate Flow FX sound. The systems use factory hanger locations for straightforward installation and are backed by Flowmaster's Lifetime Limited Warranty. Exact piping, exit style, tip configuration, and other specifications vary by part number, so customers should select the correct configuration for their truck and desired exhaust layout.
