Vehicle Fitment

• 2021-2026 Ford F-150 (2.7L EcoBoost V6, All Cab/Bed Configurations)
• 2021-2026 Ford F-150 (3.5L EcoBoost V6, All Cab/Bed Configurations)
• 2021-2026 Ford F-150 (5.0L V8, All Cab/Bed Configurations)

Fitment Notes

• Excludes F-150 PowerBoost Hybrid (3.5L hybrid) - PowerBoost requires a dedicated resonator-back system
• Excludes F-150 Tremor - Tremor requires a Tremor-specific exhaust system
• Excludes F-150 Raptor - Raptor requires a Raptor-specific exhaust system
• Direct bolt-on installation using factory OEM hangers and mounting points - no cutting or welding required
• Single side exit configuration - routes exhaust to a single outlet on the passenger side
• Black powder coating on tip and tailpipe is recommended for dry climates - prolonged exposure to road salt or heavy moisture can affect the coating finish
• This is a cat-back system - does not replace, modify, or affect any emissions control equipment

Features

• High-heat black powder-coated tailpipe and tip deliver a stealthy, murdered-out aesthetic that pairs aggressively with any F-150 exterior color
• Heavy-gauge aluminized steel tubing throughout the system provides solid resistance to dings and dents from road debris
• Smooth mandrel-bent 3-inch tubing reduces backpressure for improved exhaust flow, throttle response, and engine efficiency
• Street Profile sound tuning delivers a deeper, more assertive exhaust note under acceleration without excessive cabin drone at highway speeds
• Dyno-proven on MBRP's in-house chassis dynamometer - up to 11 HP and 8 ft-lbs of torque on the 5.0L platform with a 28% improvement in exhaust flow
• Bolt-on design uses factory OEM hangers - no welding or cutting required
• 1-Year Warranty on black powder-coat finish; 3-Year Warranty on exhaust system components

Product Description

The MBRP S5277BLK is an Armor BLK cat-back exhaust system built for the 2021-2026 Ford F-150 equipped with the 2.7L EcoBoost, 3.5L EcoBoost, or 5.0L V8 engine. Sharing the same mandrel-bent 3-inch tubing construction and performance engineering as the Armor Lite series, this system adds a high-heat black powder-coated finish to the tailpipe and tip for a stealthy, blacked-out appearance that makes a bold visual statement at the rear of the truck. Street Profile sound tuning produces a noticeably deeper, more aggressive exhaust note under acceleration while remaining composed and drone-free at highway cruising speeds.

Dyno-proven on MBRP's in-house chassis dynamometer, this system delivers up to 11 horsepower and 8 ft-lbs of torque on the 5.0L platform, along with a 28% improvement in exhaust flow. Installation is completely bolt-on using factory OEM hangers - no cutting or welding required. The black coating is optimized for dry-climate use and is not recommended for prolonged road salt or moisture exposure. This system is not compatible with the F-150 PowerBoost Hybrid, Tremor, or Raptor. Backed by MBRP's 1-Year Warranty on the black powder-coat finish and 3-Year Warranty on all exhaust components.
