The Gibson Dual Extreme cat-back for 2011–2013 Ford F-150 FX2 5.0L is an aluminized system tuned for improved acceleration, towing and low-end torque. As the brand’s top-performing exhaust, it makes maximum torque and horsepower at low RPMs (1800–3000) and typically delivers 10–15 horsepower gains with 15–20 lb-ft more torque. Exiting behind the rear tire, it is quieter in the cab than many performance systems and installs bolt-on with included hardware; no welding required and backed by a Lifetime Limited Warranty.
