Flow Fx Extreme Cat-Back Exhaust System Fits 2009-2014 Ford F-150 3.5L, 4.6L, 5.0L, 5.4L Flow Fx Extreme Stainless Steel 3.0 Inch Cat-Back Exhaust System - Flowmaster - 717980

Flowmaster introduces our new Flow FX Extreme stainless-steel cat-back exhaust system for the 2009-2014 Ford F-150 with the 3.5L Ecoboost, 4.6L, 5.0L and 5.4L 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.
