Description & Features
Flowmaster 717978 Flow FX Extreme Cat-Back Exhaust System
Flowmaster introduces our new Flow FX Extreme stainless steel cat-back exhaust system for the 2015-2020 Ford F-150 with the 2.7L, 3.3L, 3.5L, and 5.0L engines. This system uses a Flow FX series muffler for a deep powerful sound and increased performance. 3.0-inch mandrel bent 409 stainless steel tubing is used for maximum exhaust flow and durability. The system has a turndown style dump exit right after the muffler to eliminate the over-axle tailpipe. This elimination of the tailpipe helps to improve ground clearance and departure angle when you are driving in more extreme off-road situations. All of the necessary hardware is included and factory mounting locations are used for an easy installation. Backed by Flowmaster's Lifetime Limited Warranty.
