MBRP S5261BLK Armor BLK 3in Race Cat-Back Pre-Axle Exhaust for 09-14 Ford F-150

Vehicle Fitment

• 2009-2014 Ford F-150 (3.5L EcoBoost V6; All Cab/Box Configurations; 2WD/4WD)
• 2009-2014 Ford F-150 (3.7L V6; All Cab/Box Configurations; 2WD/4WD)
• 2009-2014 Ford F-150 (5.0L V8; All Cab/Box Configurations; 2WD/4WD)

Fitment Notes

• Compatible with 3.5L EcoBoost, 3.7L V6, and 5.0L V8 engines only - does not fit the 4.6L V8, 5.4L V8, or 6.2L V8 variants in this generation
• Dual pre-axle exit configuration - tips exit ahead of the rear axle on both sides of the truck, not behind the rear bumper; this is a race-inspired layout distinct from side exit or rear bumper exit configurations
• Black powder coating on the tailpipes and tips is warranted for 1 year against factory defects; all remaining exhaust components carry a 3-year warranty
• Black coating is best suited for dry climates - aluminized steel base material is not recommended for heavy snow-belt or high-salt environments

Features

• Race Profile sound tuning delivers MBRP's most aggressive exhaust note - engineered for maximum volume and character under acceleration, producing a head-turning exhaust tone that sets the S5261BLK apart from MBRP's Street and Tour Profile offerings
• Dual pre-axle exit configuration - both tips emerge ahead of the rear axle along the sides of the truck, giving the F-150 a race-inspired appearance reminiscent of purpose-built performance trucks
• Full cat-back design replaces all factory exhaust from the catalytic converter rearward for the maximum flow improvement available in a complete bolt-on package
• High-heat black powder-coated tailpipes and tips deliver the fully blacked-out, stealthy aesthetic of the Armor BLK series - engineered specifically for murdered-out builds where polished or bright tips would disrupt the look
• Black-coated T304 stainless steel dual-wall angle-cut tips maintain the blacked-out appearance while providing the functional benefit of dual-wall construction, shielding surrounding body panels from exhaust heat
• Large 4.5-inch tip outlets command attention at both pre-axle exits and reinforce the aggressive, race-derived visual character of the system
• 16-gauge aluminized steel construction with fully sealed seams provides solid resistance against early rust-through on non-coated system sections
• Mandrel-bent 3-inch tubing maintains a consistent internal diameter through all bends, reducing backpressure and lowering exhaust gas temperatures versus the factory system
• Backed by MBRP's split warranty: 1-Year on black powder coating, 3-Year on all exhaust components

Product Description

The MBRP S5261BLK is a 3-inch Armor BLK dual pre-axle exit cat-back exhaust system engineered for the 2009-2014 Ford F-150 equipped with the 3.5L EcoBoost, 3.7L V6, or 5.0L V8 engine. It is the blacked-out Armor BLK variant of the S5261 pre-axle platform - sharing the same routing geometry and Race Profile sound tuning as the S5261AL, but with the tailpipes and tips finished in high-heat black powder coating for a fully murdered-out appearance. Race Profile is MBRP's most aggressive sound tuning, engineered to produce the maximum exhaust note under acceleration, making the S5261BLK the choice for F-150 owners who want the loudest, most dramatic MBRP sound experience available for this platform.

The dual pre-axle exit layout is the defining visual characteristic of this system - both 4.5-inch black-coated dual-wall tips emerge ahead of the rear axle along the sides of the truck rather than behind the rear bumper or at the bumper corners, giving the F-150 a race-truck stance that stands apart from every other exit style in the lineup. The dual-wall tip construction keeps exhaust heat away from surrounding body panels while keeping the black-coated finish consistent throughout. The aluminized steel body uses fully sealed seams to resist early rust-through, and welded-on hanger brackets align with factory OEM mounting locations.

Unlike the S5232AL and S5234AL which are restricted to specific cab and box combinations, the S5261BLK is confirmed by MBRP to fit all cab and box configurations of the 2009-2014 F-150 across the 3.5L EcoBoost, 3.7L V6, and 5.0L V8 engine variants. As with all Armor BLK products, the black powder coating is warranted for 1 year against factory defects, while all exhaust components carry MBRP's 3-year warranty. Aluminized steel is recommended for dry-climate use and is not suited for high-salt or heavy snow-belt environments where the underlying aluminized steel would be accelerated toward early corrosion.
