Built specifically for the 2011-2014 Ford F-150, the MBRP S5261409 cat-back exhaust routes 3-inch mandrel-bent tubing from the catalytic converters to a pair of pre-axle exits, capped with 4.5-inch OD tips for a clean, purposeful look that sits tight to the truck.
Pre-axle dual outlet placement. Exiting ahead of the rear axle keeps the tips tucked and protected from trail debris, trailer hitches, and loading-dock contact. The dual-outlet configuration delivers a balanced exhaust note without the drone that plagues single-exit setups at highway cruise.
T409 stainless construction throughout. T409 stainless steel resists the heat cycles, road salt, and moisture that corrode mild-steel systems. The finish holds up through seasons of use without the weight penalty of heavier aluminized alternatives.
3-inch mandrel-bent tubing. Smooth, constant-diameter bends maintain exhaust velocity through every curve in the system. Reducing restriction in the exhaust path gives the engine more room to breathe across the RPM range, which translates to a stronger pull when towing or hauling.
Wide trim-level compatibility. The S5261409 fits XL, XLT, STX, FX2, FX4, Lariat, King Ranch, and Platinum F-150s from 2011 through 2014, making it a straightforward choice across nearly the entire model range.
