Gibson 11-14 Ford F-150 FX4 3.5L 3in Cat-Back Single Exhaust - Stainless

The Gibson Superflow™ muffler in this cat-back system is constructed from polished stainless steel with a baffled and chambered design, meaning it doesn't rely on internal packing to control sound. This approach helps it achieve a notable increase in horsepower and torque, especially in the low-end RPM range where you need it most for towing, hill climbing, and passing. Dyno tests show gains of 10-15 horsepower and 15-20 lb-ft of torque, giving your 2011-2014 Ford F-150 FX4 3.5L a significant boost in performance.

This system is designed for a hassle-free, bolt-on installation, utilizing factory-style hangers and including all necessary hardware, so no welding is required. The mandrel-bent stainless steel tubing ensures consistent exhaust flow, while the single-side exit behind the rear tire, capped with a polished stainless steel slash-cut tip, looks professional and keeps interior cabin noise to a minimum, avoiding the drone often found in other performance exhaust systems. Gibson backs this well-built system with a Lifetime Limited Warranty.
