The Gibson Dual Split cat-back exhaust for 2011–2013 Ford F-150 FX2 3.5L is a stainless system tuned to reduce backpressure and raise torque and power, typically yielding 15–20 hp. Polished dual tips exit straight from the rear and the baffled muffler limits interior drone. It installs bolt-on with factory-style hangers and hardware included, requires no welding, and is covered by a Gibson lifetime limited warranty.
